01 Jump starting the psych packagendasha guide for the impatient

You have installed psych (section 2) and you want to use it without reading much moreWhat should you do

1 Activate the psych package

library(psych)

2 Input your data (section 31) There are two ways to do this

bull Find and read standard files using readfile This will open a search windowfor your operating system which you can use to find the file If the file has asuffix of text txt csv data sav r R rds Rds rda Rda rdata orRData then the file will be opened and the data will be read in

myData lt- readfile() find the appropriate file using your normal operating system

bull Alternatively go to your friendly text editor or data manipulation program(eg Excel) and copy the data to the clipboard Include a first line that has thevariable labels Paste it into psych using the readclipboardtab command

myData lt- readclipboardtab() if on the clipboard

Note that there are number of options for readclipboard for reading in Excelbased files lower triangular files etc

3 Make sure that what you just read is right Describe it (section 33) and perhapslook at the first and last few lines If you have multiple groups try describeBy

dim(myData) What are the dimensions of the data

describe(myData) or

descrbeBy(myDatagroups=mygroups) for descriptive statistics by groups

headTail(myData) show the first and last n lines of a file

4 Look at the patterns in the data If you have fewer than about 12 variables lookat the SPLOM (Scatter Plot Matrix) of the data using pairspanels (section 341)Then use the outlier function to detect outliers

pairspanels(myData)

outlier(myData)

5 Note that you might have some weird subjects probably due to data entry errorsEither edit the data by hand (use the edit command) or just scrub the data (section332)

cleaned lt- scrub(myData max=9) eg change anything great than 9 to NA

6 Graph the data with error bars for each variable (section 343)

errorbars(myData)

7 Find the correlations of all of your data lowerCor will by default find the pairwisecorrelations round them to 2 decimals and display the lower off diagonal matrix

bull Descriptively (just the values) (section 347)

r lt- lowerCor(myData) The correlation matrix rounded to 2 decimals

bull Graphically (section 348) Another way is to show a heat map of the correla-tions with the correlation values included

corPlot(r) examine the many options for this function

bull Inferentially (the values the ns and the p values) (section 35)

corrtest(myData)

8 Apply various regression models

Several functions are meant to do multiple regressions either from the raw data orfrom a variancecovariance matrix or a correlation matrix

bull setCor will take raw data or a correlation matrix and find (and graph the pathdiagram) for multiple y variables depending upon multiple x variables

myData lt- satact

colnames(myData) lt- c(mod1med1x1x2y1y2)

setCor(y = c( y1 y2) x = c(x1x2) data = myData)

bull mediate will take raw data or a correlation matrix and find (and graph the pathdiagram) for multiple y variables depending upon multiple x variables mediatedthrough a mediation variable It then tests the mediation effect using a bootstrap

mediate(y = c( y1 y2) x = c(x1x2) m= med1 data = myData)

bull mediate will take raw data and find (and graph the path diagram) a moderatedmultiple regression model for multiple y variables depending upon multiple xvariables mediated through a mediation variable It then tests the mediationeffect using a boot strap

mediate(y = c( y1 y2) x = c(x1x2) m= med1 mod = mod1 data = myData)

02 Psychometric functions are summarized in the second vignette

Many additional functions particularly designed for basic and advanced psychomet-rics are discussed more fully in the Overview Vignette A brief review of the functionsavailable is included here In addition there are helpful tutorials for Finding omegaHow to score scales and find reliability and for Using psych for factor analysis athttppersonality-projectorgr

bull Test for the number of factors in your data using parallel analysis (faparallelsection ) or Very Simple Structure (vss )

faparallel(myData)

vss(myData)

bull Factor analyze (see section ) the data with a specified number of factors(the default is 1) the default method is minimum residual the default rotationfor more than one factor is oblimin There are many more possibilities (seesections -) Compare the solution to a hierarchical cluster analysis using theICLUST algorithm (Revelle 1979) (see section ) Also consider a hierarchicalfactor solution to find coefficient ω (see )

fa(myData)

iclust(myData)

omega(myData)

If you prefer to do a principal components analysis you may use the principalfunction The default is one component

principal(myData)

bull Some people like to find coefficient α as an estimate of reliability This may bedone for a single scale using the alpha function (see ) Perhaps more usefulis the ability to create several scales as unweighted averages of specified itemsusing the scoreItems function (see ) and to find various estimates of internalconsistency for these scales find their intercorrelations and find scores for allthe subjects

alpha(myData) score all of the items as part of one scale

myKeys lt- makekeys(nvar=20list(first = c(1-35-7810)second=c(24-61115-16)))

myscores lt- scoreItems(myKeysmyData) form several scales

myscores show the highlights of the results

At this point you have had a chance to see the highlights of the psych package and to dosome basic (and advanced) data analysis You might find reading this entire vignette aswell as the Overview Vignette to be helpful to get a broader understanding of what can bedone in R using the psych Remember that the help command () is available for everyfunction Try running the examples for each help page

1 Overview of this and related documents

The psych package (Revelle 2015) has been developed at Northwestern University since2005 to include functions most useful for personality psychometric and psychological re-search The package is also meant to supplement a text on psychometric theory (Revelleprep) a draft of which is available at httppersonality-projectorgrbook

Some of the functions (eg readfile readclipboard describe pairspanels scat-terhist errorbars multihist bibars) are useful for basic data entry and descrip-tive analyses

Psychometric applications emphasize techniques for dimension reduction including factoranalysis cluster analysis and principal components analysis The fa function includesfive methods of factor analysis (minimum residual principal axis weighted least squaresgeneralized least squares and maximum likelihood factor analysis) Principal ComponentsAnalysis (PCA) is also available through the use of the principal or pca functions De-termining the number of factors or components to extract may be done by using the VerySimple Structure (Revelle and Rocklin 1979) (vss) Minimum Average Partial correlation(Velicer 1976) (MAP) or parallel analysis (faparallel) criteria These and several othercriteria are included in the nfactors function Two parameter Item Response Theory(IRT) models for dichotomous or polytomous items may be found by factoring tetra-

choric or polychoric correlation matrices and expressing the resulting parameters interms of location and discrimination using irtfa

Bifactor and hierarchical factor structures may be estimated by using Schmid Leimantransformations (Schmid and Leiman 1957) (schmid) to transform a hierarchical factorstructure into a bifactor solution (Holzinger and Swineford 1937) Higher order modelscan also be found using famulti

Scale construction can be done using the Item Cluster Analysis (Revelle 1979) (iclust)function to determine the structure and to calculate reliability coefficients α (Cronbach1951)(alpha scoreItems scoremultiplechoice) β (Revelle 1979 Revelle and Zin-barg 2009) (iclust) and McDonaldrsquos ωh and ωt (McDonald 1999) (omega) Guttmanrsquos sixestimates of internal consistency reliability (Guttman (1945) as well as additional estimates(Revelle and Zinbarg 2009) are in the guttman function The six measures of Intraclasscorrelation coefficients (ICC) discussed by Shrout and Fleiss (1979) are also available

For data with a a multilevel structure (eg items within subjects across time or itemswithin subjects across groups) the describeBy statsBy functions will give basic descrip-tives by group StatsBy also will find within group (or subject) correlations as well as thebetween group correlation

multilevelreliability mlr will find various generalizability statistics for subjects over

time and items mlPlot will graph items over for each subject mlArrange converts widedata frames to long data frames suitable for multilevel modeling

Graphical displays include Scatter Plot Matrix (SPLOM) plots using pairspanels cor-relation ldquoheat mapsrdquo (corPlot) factor cluster and structural diagrams using fadiagramiclustdiagram structurediagram and hetdiagram as well as item response charac-teristics and item and test information characteristic curves plotirt and plotpoly

This vignette is meant to give an overview of the psych package That is it is meantto give a summary of the main functions in the psych package with examples of howthey are used for data description dimension reduction and scale construction The ex-tended user manual at psych_manualpdf includes examples of graphic output and moreextensive demonstrations than are found in the help menus (Also available at http

personality-projectorgrpsych_manualpdf) The vignette psych for sem atpsych_for_sempdf discusses how to use psych as a front end to the sem package of JohnFox (Fox et al 2012) (The vignette is also available at httppersonality-project

2 Getting started

Some of the functions described in the Overview Vignette require other packages This isnot the case for the functions listed in this Introduction Particularly useful for rotatingthe results of factor analyses (from eg fa factorminres factorpa factorwlsor principal) or hierarchical factor models using omega or schmid is the GPArotationpackage These and other useful packages may be installed by first installing and thenusing the task views (ctv) package to install the ldquoPsychometricsrdquo task view but doing itthis way is not necessary

installpackages(ctv)

library(ctv)

taskviews(Psychometrics)

The ldquoPsychometricsrdquo task view will install a large number of useful packages To installthe bare minimum for the examples in this vignette it is necessary to install just 3 pack-ages

installpackages(list(c(GPArotationmnormt)

Because of the difficulty of installing the package Rgraphviz alternative graphics have beendeveloped and are available as diagram functions If Rgraphviz is available some functionswill take advantage of it An alternative is to useldquodotrdquooutput of commands for any externalgraphics package that uses the dot language

3 Basic data analysis

A number of psych functions facilitate the entry of data and finding basic descriptivestatistics

Remember to run any of the psych functions it is necessary to make the package activeby using the library command

library(psych)

The other packages once installed will be called automatically by psych

It is possible to automatically load psych and other functions by creating and then savinga ldquoFirstrdquo function eg

First lt- function(x) library(psych)

31 Getting the data by using readfile

Although many find copying the data to the clipboard and then using the readclipboardfunctions (see below) a helpful alternative is to read the data in directly This can be doneusing the readfile function which calls filechoose to find the file and then based uponthe suffix of the file chooses the appropriate way to read it For files with suffixes of txttext r rds rda csv xpt or sav the file will be read correctly

mydata lt- readfile()

If the file contains Fixed Width Format (fwf) data the column information can be specifiedwith the widths command

mydata lt- readfile(widths = c(4rep(135)) will read in a file without a header row and 36 fields the first of which is 4 colums the rest of which are 1 column each

If the file is a RData file (with suffix of RData Rda rda Rdata or rdata) the objectwill be loaded Depending what was stored this might be several objects If the file is asav file from SPSS it will be read with the most useful default options (converting the fileto a dataframe and converting character fields to numeric) Alternative options may bespecified If it is an export file from SAS (xpt or XPT) it will be read csv files (comma

separated files) normal txt or text files data or dat files will be read as well These areassumed to have a header row of variable labels (header=TRUE) If the data do not havea header row you must specify readfile(header=FALSE)

To read SPSS files and to keep the value labels specify usevaluelabels=TRUE

myspss lt- readfile(usevaluelabels=TRUE) this will keep the value labels for sav files

32 Data input from the clipboard

There are of course many ways to enter data into R Reading from a local file usingreadtable is perhaps the most preferred However many users will enter their datain a text editor or spreadsheet program and then want to copy and paste into R Thismay be done by using readtable and specifying the input file as ldquoclipboardrdquo (PCs) orldquopipe(pbpaste)rdquo (Macs) Alternatively the readclipboard set of functions are perhapsmore user friendly

readclipboard is the base function for reading data from the clipboard

readclipboardcsv for reading text that is comma delimited

readclipboardtab for reading text that is tab delimited (eg copied directly from anExcel file)

readclipboardlower for reading input of a lower triangular matrix with or without adiagonal The resulting object is a square matrix

readclipboardupper for reading input of an upper triangular matrix

readclipboardfwf for reading in fixed width fields (some very old data sets)

For example given a data set copied to the clipboard from a spreadsheet just enter thecommand

mydata lt- readclipboard()

This will work if every data field has a value and even missing data are given some values(eg NA or -999) If the data were entered in a spreadsheet and the missing valueswere just empty cells then the data should be read in as a tab delimited or by using thereadclipboardtab function

gt mydata lt- readclipboard(sep=t) define the tab option or

gt mytabdata lt- readclipboardtab() just use the alternative function

For the case of data in fixed width fields (some old data sets tend to have this format)copy to the clipboard and then specify the width of each field (in the example below the

first variable is 5 columns the second is 2 columns the next 5 are 1 column the last 4 are3 columns)

gt mydata lt- readclipboardfwf(widths=c(52rep(15)rep(34))

33 Basic descriptive statistics

Once the data are read in then describe or describeBy will provide basic descriptivestatistics arranged in a data frame format Consider the data set satact which in-cludes data from 700 web based participants on 3 demographic variables and 3 abilitymeasures

describe reports means standard deviations medians min max range skew kurtosisand standard errors for integer or real data Non-numeric data although the statisticsare meaningless will be treated as if numeric (based upon the categorical coding ofthe data) and will be flagged with an

describeBy reports descriptive statistics broken down by some categorizing variable (eggender age etc)

These data may then be analyzed by groups defined in a logical statement or by some othervariable Eg break down the descriptive data for males or females These descriptivedata can also be seen graphically using the errorbarsby function (Figure 6) By settingskew=FALSE and ranges=FALSE the output is limited to the most basic statistics

331 Outlier detection using outlier

One way to detect unusual data is to consider how far each data point is from the mul-tivariate centroid of the data That is find the squared Mahalanobis distance for eachdata point and then compare these to the expected values of χ2 This produces a Q-Q(quantle-quantile) plot with the n most extreme data points labeled (Figure 1) The outliervalues are in the vector d2

332 Basic data cleaning using scrub

If after describing the data it is apparent that there were data entry errors that need tobe globally replaced with NA or only certain ranges of data will be analyzed the data canbe ldquocleanedrdquo using the scrub function

Consider a data set of 10 rows of 12 columns with values from 1 - 120 All values of columns

3 - 5 that are less than 30 40 or 50 respectively or greater than 70 in any of the threecolumns will be replaced with NA In addition any value exactly equal to 45 will be setto NA (max and isvalue are set to one value here but they could be a different value forevery column)

Note that the number of subjects for those columns has decreased and the minimums havegone up but the maximums down Data cleaning and examination for outliers should be aroutine part of any data analysis

333 Recoding categorical variables into dummy coded variables

Sometimes categorical variables (eg college major occupation ethnicity) are to be ana-lyzed using correlation or regression To do this one can form ldquodummy codesrdquo which aremerely binary variables for each category This may be done using dummycode Subse-quent analyses using these dummy coded variables may be using biserial or point biserial(regular Pearson r) to show effect sizes and may be plotted in eg spider plots

Alternatively sometimes data were coded originally as categorical (MaleFemale HighSchool some College in college etc) and you want to convert these columns of data tonumeric This is done by char2numeric

34 Simple descriptive graphics

Graphic descriptions of data are very helpful both for understanding the data as well ascommunicating important results Scatter Plot Matrices (SPLOMS) using the pairspanelsfunction are useful ways to look for strange effects involving outliers and non-linearitieserrorbarsby will show group means with 95 confidence boundaries By default er-rorbarsby and errorbars will show ldquocats eyesrdquo to graphically show the confidence

limits (Figure 6) This may be turned off by specifying eyes=FALSE densityBy or vio-

linBy may be used to show the distribution of the data in ldquoviolinrdquo plots (Figure 5) (Theseare sometimes called ldquolava-lamprdquo plots)

341 Scatter Plot Matrices

Scatter Plot Matrices (SPLOMS) are very useful for describing the data The pairspanelsfunction adapted from the help menu for the pairs function produces xy scatter plots ofeach pair of variables below the diagonal shows the histogram of each variable on thediagonal and shows the lowess locally fit regression line as well An ellipse around themean with the axis length reflecting one standard deviation of the x and y variables is alsodrawn The x axis in each scatter plot represents the column variable the y axis the rowvariable (Figure 2) When plotting many subjects it is both faster and cleaner to set theplot character (pch) to be rsquorsquo (See Figure 2 for an example)

pairspanels will show the pairwise scatter plots of all the variables as well as his-tograms locally smoothed regressions and the Pearson correlation When plottingmany data points (as in the case of the satact data it is possible to specify that theplot character is a period to get a somewhat cleaner graphic However in this figureto show the outliers we use colors and a larger plot character If we want to indicatersquosignificancersquo of the correlations by the conventional use of rsquomagic astricksrsquo we can setthe stars=TRUE option

Another example of pairspanels is to show differences between experimental groupsConsider the data in the affect data set The scores reflect post test scores on positiveand negative affect and energetic and tense arousal The colors show the results for fourmovie conditions depressing frightening movie neutral and a comedy

Yet another demonstration of pairspanels is useful when you have many subjects andwant to show the density of the distributions To do this we will use the makekeys

and scoreItems functions (discussed in the second vignette) to create scales measuringEnergetic Arousal Tense Arousal Positive Affect and Negative Affect (see the msq helpfile) We then show a pairspanels scatter plot matrix where we smooth the data pointsand show the density of the distribution by color

342 Density or violin plots

Graphical presentation of data may be shown using box plots to show the median and 25thand 75th percentiles A powerful alternative is to show the density distribution using theviolinBy function (Figure 5)

343 Means and error bars

Additional descriptive graphics include the ability to draw error bars on sets of data aswell as to draw error bars in both the x and y directions for paired data These are thefunctions errorbars errorbarsby errorbarstab and errorcrosses

errorbars show the 95 confidence intervals for each variable in a data frame or ma-trix These errors are based upon normal theory and the standard errors of the meanAlternative options include +- one standard deviation or 1 standard error If thedata are repeated measures the error bars will be reflect the between variable cor-relations By default the confidence intervals are displayed using a ldquocats eyesrdquo plotwhich emphasizes the distribution of confidence within the confidence interval

errorbarsby does the same but grouping the data by some condition

errorbarstab draws bar graphs from tabular data with error bars based upon thestandard error of proportion (σp =

radicpqN)

errorcrosses draw the confidence intervals for an x set and a y set of the same size

The use of the errorbarsby function allows for graphic comparisons of different groups(see Figure 6) Five personality measures are shown as a function of high versus low scoreson a ldquolierdquo scale People with higher lie scores tend to report being more agreeable consci-entious and less neurotic than people with lower lie scores The error bars are based uponnormal theory and thus are symmetric rather than reflect any skewing in the data

Although not recommended it is possible to use the errorbars function to draw bargraphs with associated error bars (This kind of dynamite plot (Figure 8) can be verymisleading in that the scale is arbitrary Go to a discussion of the problems in presentingdata this way at httpemdbolkerwikidotcomblogdynamite In the example shownnote that the graph starts at 0 although is out of the range This is a function of usingbars which always are assumed to start at zero Consider other ways of showing yourdata

344 Error bars for tabular data

However it is sometimes useful to show error bars for tabular data either found by thetable function or just directly input These may be found using the errorbarstab

345 Two dimensional displays of means and errors

Yet another way to display data for different conditions is to use the errorCrosses func-tion For instance the effect of various movies on both ldquoEnergetic Arousalrdquo and ldquoTenseArousalrdquo can be seen in one graph and compared to the same movie manipulations onldquoPositive Affectrdquo and ldquoNegative Affectrdquo Note how Energetic Arousal is increased by threeof the movie manipulations but that Positive Affect increases following the Happy movieonly

347 Correlational structure

There are many ways to display correlations Tabular displays are probably the mostcommon The output from the cor function in core R is a rectangular matrix lowerMat

will round this to (2) digits and then display as a lower off diagonal matrix lowerCor

calls cor with use=lsquopairwisersquo method=lsquopearsonrsquo as default values and returns (invisibly)the full correlation matrix and displays the lower off diagonal matrix

348 Heatmap displays of correlational structure

Perhaps a better way to see the structure in a correlation matrix is to display a heat mapof the correlations This is just a matrix color coded to represent the magnitude of thecorrelation This is useful when considering the number of factors in a data set Considerthe Thurstone data set which has a clear 3 factor solution (Figure 11) or a simulated dataset of 24 variables with a circumplex structure (Figure 12) The color coding representsa ldquoheat maprdquo of the correlations with darker shades of red representing stronger negativeand darker shades of blue stronger positive correlations As an option the value of thecorrelation can be shown

Yet another way to show structure is to use ldquospiderrdquo plots Particularly if variables areordered in some meaningful way (eg in a circumplex) a spider plot will show this structureeasily This is just a plot of the magnitude of the correlation as a radial line with lengthranging from 0 (for a correlation of -1) to 1 (for a correlation of 1) (See Figure 13)

35 Testing correlations

Correlations are wonderful descriptive statistics of the data but some people like to testwhether these correlations differ from zero or differ from each other The cortest func-tion (in the stats package) will test the significance of a single correlation and the rcorr

function in the Hmisc package will do this for many correlations In the psych packagethe corrtest function reports the correlation (Pearson Spearman or Kendall) betweenall variables in either one or two data frames or matrices as well as the number of obser-vations for each case and the (two-tailed) probability for each correlation Unfortunatelythese probability values have not been corrected for multiple comparisons and so shouldbe taken with a great deal of salt Thus in corrtest and corrp the raw probabilitiesare reported below the diagonal and the probabilities adjusted for multiple comparisonsusing (by default) the Holm correction are reported above the diagonal (Table 1) (See thepadjust function for a discussion of Holm (1979) and other corrections)

Testing the difference between any two correlations can be done using the rtest functionThe function actually does four different tests (based upon an article by Steiger (1980)

To test whether a matrix of correlations differs from what would be expected if the popu-lation correlations were all zero the function cortest follows Steiger (1980) who pointedout that the sum of the squared elements of a correlation matrix or the Fisher z scoreequivalents is distributed as chi square under the null hypothesis that the values are zero(ie elements of the identity matrix) This is particularly useful for examining whethercorrelations in a single matrix differ from zero or for comparing two matrices Althoughobvious cortest can be used to test whether the satact data matrix produces non-zerocorrelations (it does) This is a much more appropriate test when testing whether a residualmatrix differs from zero

36 Polychoric tetrachoric polyserial and biserial correlations

The Pearson correlation of dichotomous data is also known as the φ coefficient If thedata eg ability items are thought to represent an underlying continuous although latentvariable the φ will underestimate the value of the Pearson applied to these latent variablesOne solution to this problem is to use the tetrachoric correlation which is based uponthe assumption of a bivariate normal distribution that has been cut at certain points Thedrawtetra function demonstrates the process (Figure 14) This is also shown in termsof dichotomizing the bivariate normal density function using the drawcor function (Fig-ure 15) A simple generalization of this to the case of the multiple cuts is the polychoric

correlation

Other estimated correlations based upon the assumption of bivariate normality with cutpoints include the biserial and polyserial correlation

If the data are a mix of continuous polytomous and dichotomous variables the mixedcor

function will calculate the appropriate mixture of Pearson polychoric tetrachoric biserialand polyserial correlations

The correlation matrix resulting from a number of tetrachoric or polychoric correlationmatrix sometimes will not be positive semi-definite This will sometimes happen if thecorrelation matrix is formed by using pair-wise deletion of cases The corsmooth functionwill adjust the smallest eigen values of the correlation matrix to make them positive rescaleall of them to sum to the number of variables and produce aldquosmoothedrdquocorrelation matrixAn example of this problem is a data set of burt which probably had a typo in the originalcorrelation matrix Smoothing the matrix corrects this problem

4 Multilevel modeling

Correlations between individuals who belong to different natural groups (based upon egethnicity age gender college major or country) reflect an unknown mixture of the pooledcorrelation within each group as well as the correlation of the means of these groupsThese two correlations are independent and do not allow inferences from one level (thegroup) to the other level (the individual) When examining data at two levels (eg theindividual and by some grouping variable) it is useful to find basic descriptive statistics(means sds ns per group within group correlations) as well as between group statistics(over all descriptive statistics and overall between group correlations) Of particular use

is the ability to decompose a matrix of correlations at the individual level into correlationswithin group and correlations between groups

41 Decomposing data into within and between level correlations usingstatsBy

There are at least two very powerful packages (nlme and multilevel) which allow for complexanalysis of hierarchical (multilevel) data structures statsBy is a much simpler functionto give some of the basic descriptive statistics for two level models

This follows the decomposition of an observed correlation into the pooled correlation withingroups (rwg) and the weighted correlation of the means between groups which is discussedby Pedhazur (1997) and by Bliese (2009) in the multilevel package

rxy = ηxwg lowastηywg lowast rxywg + ηxbg lowastηybg lowast rxybg (1)

where rxy is the normal correlation which may be decomposed into a within group andbetween group correlations rxywg and rxybg and η (eta) is the correlation of the data withthe within group values or the group means

42 Generating and displaying multilevel data

withinBetween is an example data set of the mixture of within and between group cor-relations The within group correlations between 9 variables are set to be 1 0 and -1while those between groups are also set to be 1 0 -1 These two sets of correlations arecrossed such that V1 V4 and V7 have within group correlations of 1 as do V2 V5 andV8 and V3 V6 and V9 V1 has a within group correlation of 0 with V2 V5 and V8and a -1 within group correlation with V3 V6 and V9 V1 V2 and V3 share a betweengroup correlation of 1 as do V4 V5 and V6 and V7 V8 and V9 The first group has a 0between group correlation with the second and a -1 with the third group See the help filefor withinBetween to display these data

simmultilevel will generate simulated data with a multilevel structure

The statsByboot function will randomize the grouping variable ntrials times and find thestatsBy output This can take a long time and will produce a great deal of output Thisoutput can then be summarized for relevant variables using the statsBybootsummary

function specifying the variable of interest

Consider the case of the relationship between various tests of ability when the data aregrouped by level of education (statsBy(satact)) or when affect data are analyzed withinand between an affect manipulation (statsBy(affect) )

43 Factor analysis by groups

Confirmatory factor analysis comparing the structures in multiple groups can be donein the lavaan package However for exploratory analyses of the structure within each ofmultiple groups the faBy function may be used in combination with the statsBy functionFirst run pfunstatsBy with the correlation option set to TRUE and then run faBy on theresulting output

sb lt- statsBy(bfi[c(12527)] group=educationcors=TRUE)

faBy(sbnfactors=5) find the 5 factor solution for each education level

5 Multiple Regression mediation moderation and set cor-relations

The typical application of the lm function is to do a linear model of one Y variable as afunction of multiple X variables Because lm is designed to analyze complex interactions itrequires raw data as input It is however sometimes convenient to do multiple regressionfrom a correlation or covariance matrix This is done using the setCor which will workwith either raw data covariance matrices or correlation matrices

51 Multiple regression from data or correlation matrices

The setCor function will take a set of y variables predicted from a set of x variablesperhaps with a set of z covariates removed from both x and y Consider the Thurstonecorrelation matrix and find the multiple correlation of the last five variables as a functionof the first 4

52 Mediation and Moderation analysis

Although multiple regression is a straightforward method for determining the effect ofmultiple predictors (x12i) on a criterion variable y some prefer to think of the effect ofone predictor x as mediated by another variable m (Preacher and Hayes 2004) Thuswe we may find the indirect path from x to m and then from m to y as well as the directpath from x to y Call these paths a b and c respectively Then the indirect effect of xon y through m is just ab and the direct effect is c Statistical tests of the ab effect arebest done by bootstrapping

Consider the example from Preacher and Hayes (2004) as analyzed using the mediate

function and the subsequent graphic from mediatediagram The data are found in theexample for mediate

Call mediate(y = SATIS x = THERAPY m = ATTRIB data = sobel)

The DV (Y) was SATIS The IV (X) was THERAPY The mediating variable(s) = ATTRIB

Direct effect (c) of THERAPY on SATIS removing ATTRIB = 043 SE = 032 t direct = 135 with probability = 019

Indirect effect (ab) of THERAPY on SATIS through ATTRIB = 033

53 Set Correlation

An important generalization of multiple regression and multiple correlation is set correla-tion developed by Cohen (1982) and discussed by Cohen et al (2003) Set correlation isa multivariate generalization of multiple regression and estimates the amount of varianceshared between two sets of variables Set correlation also allows for examining the relation-ship between two sets when controlling for a third set This is implemented in the setCor

function Set correlation is

R2 = 1minusn

prodi=1

(1minusλi)

where λi is the ith eigen value of the eigen value decomposition of the matrix

R = Rminus1xx RxyRminus1

xx Rminus1xy

Unfortunately there are several cases where set correlation will give results that are muchtoo high This will happen if some variables from the first set are highly related to thosein the second set even though most are not In this case although the set correlationcan be very high the degree of relationship between the sets is not as high In thiscase an alternative statistic based upon the average canonical correlation might be moreappropriate

setCor has the additional feature that it will calculate multiple and partial correlationsfrom the correlation or covariance matrix rather than the original data

Consider the correlations of the 6 variables in the satact data set First do the normalmultiple regression and then compare it with the results using setCor Two things tonotice setCor works on the correlation or covariance or raw data matrix and thus ifusing the correlation matrix will report standardized or raw β weights Secondly it ispossible to do several multiple regressions simultaneously If the number of observationsis specified or if the analysis is done on raw data statistical tests of significance areapplied

For this example the analysis is done on the correlation matrix rather than the rawdata

6 Converting output to APA style tables using LATEX

Although for most purposes using the Sweave or KnitR packages produces clean outputsome prefer output pre formatted for APA style tables This can be done using the xtablepackage for almost anything but there are a few simple functions in psych for the mostcommon tables fa2latex will convert a factor analysis or components analysis output toa LATEXtable cor2latex will take a correlation matrix and show the lower (or upper diag-onal) irt2latex converts the item statistics from the irtfa function to more convenient

LATEXoutput and finally df2latex converts a generic data frame to LATEX

An example of converting the output from fa to LATEXappears in Table 2

7 Miscellaneous functions

A number of functions have been developed for some very specific problems that donrsquot fitinto any other category The following is an incomplete list Look at the Index for psychfor a list of all of the functions

blockrandom Creates a block randomized structure for n independent variables Usefulfor teaching block randomization for experimental design

df2latex is useful for taking tabular output (such as a correlation matrix or that of de-

scribe and converting it to a LATEX table May be used when Sweave is not conve-nient

cor2latex Will format a correlation matrix in APA style in a LATEX table See alsofa2latex and irt2latex

cosinor One of several functions for doing circular statistics This is important whenstudying mood effects over the day which show a diurnal pattern See also circa-

dianmean circadiancor and circadianlinearcor for finding circular meanscircular correlations and correlations of circular with linear data

fisherz Convert a correlation to the corresponding Fisher z score

geometricmean also harmonicmean find the appropriate mean for working with differentkinds of data

ICC and cohenkappa are typically used to find the reliability for raters

headtail combines the head and tail functions to show the first and last lines of a dataset or output

topBottom Same as headtail Combines the head and tail functions to show the first andlast lines of a data set or output but does not add ellipsis between

mardia calculates univariate or multivariate (Mardiarsquos test) skew and kurtosis for a vectormatrix or dataframe

prep finds the probability of replication for an F t or r and estimate effect size

partialr partials a y set of variables out of an x set and finds the resulting partialcorrelations (See also setcor)

rangeCorrection will correct correlations for restriction of range

reversecode will reverse code specified items Done more conveniently in most psychfunctions but supplied here as a helper function when using other packages

superMatrix Takes two or more matrices eg A and B and combines them into a ldquoSupermatrixrdquo with A on the top left B on the lower right and 0s for the other twoquadrants A useful trick when forming complex keys or when forming exampleproblems

8 Data sets

A number of data sets for demonstrating psychometric techniques are included in thepsych package These include six data sets showing a hierarchical factor structure (fivecognitive examples Thurstone Thurstone33 Holzinger Bechtoldt1 Bechtoldt2and one from health psychology Reise) One of these (Thurstone) is used as an examplein the sem package as well as McDonald (1999) The original data are from Thurstone andThurstone (1941) and reanalyzed by Bechtoldt (1961) Personality item data representingfive personality factors on 25 items (bfi) or 13 personality inventory scores (epibfi) and14 multiple choice iq items (iqitems) The vegetables example has paired comparisonpreferences for 9 vegetables This is an example of Thurstonian scaling used by Guilford(1954) and Nunnally (1967) Other data sets include cubits peas and heights fromGalton

Thurstone Holzinger-Swineford (1937) introduced the bifactor model of a general factorand uncorrelated group factors The Holzinger correlation matrix is a 14 14 matrixfrom their paper The Thurstone correlation matrix is a 9 9 matrix of correlationsof ability items The Reise data set is 16 16 correlation matrix of mental healthitems The Bechtholdt data sets are both 17 x 17 correlation matrices of ability tests

bfi 25 personality self report items taken from the International Personality Item Pool(ipiporiorg) were included as part of the Synthetic Aperture Personality Assessment(SAPA) web based personality assessment project The data from 2800 subjects areincluded here as a demonstration set for scale construction factor analysis and ItemResponse Theory analyses

satact Self reported scores on the SAT Verbal SAT Quantitative and ACT were col-lected as part of the Synthetic Aperture Personality Assessment (SAPA) web basedpersonality assessment project Age gender and education are also reported Thedata from 700 subjects are included here as a demonstration set for correlation andanalysis

epibfi A small data set of 5 scales from the Eysenck Personality Inventory 5 from a Big 5inventory a Beck Depression Inventory and State and Trait Anxiety measures Usedfor demonstrations of correlations regressions graphic displays

iq 14 multiple choice ability items were included as part of the Synthetic Aperture Person-ality Assessment (SAPA) web based personality assessment project The data from1000 subjects are included here as a demonstration set for scoring multiple choiceinventories and doing basic item statistics

galton Two of the earliest examples of the correlation coefficient were Francis Galtonrsquosdata sets on the relationship between mid parent and child height and the similarity ofparent generation peas with child peas galton is the data set for the Galton heightpeas is the data set Francis Galton used to ntroduce the correlation coefficient withan analysis of the similarities of the parent and child generation of 700 sweet peas

Dwyer Dwyer (1937) introduced a method for factor extension (see faextension thatfinds loadings on factors from an original data set for additional (extended) variablesThis data set includes his example

miscellaneous cities is a matrix of airline distances between 11 US cities and maybe used for demonstrating multiple dimensional scaling vegetables is a classicdata set for demonstrating Thurstonian scaling and is the preference matrix of 9vegetables from Guilford (1954) Used by Guilford (1954) Nunnally (1967) Nunnallyand Bernstein (1984) this data set allows for examples of basic scaling techniques
