Some Analysis of Some Perch Catch Data
56 perch were caught in a freshwater lake in Finland
Their weights, lengths, heights and widths were recorded
It may be anticipated that thefish's weights depend on their lengths, heights and widths whose product is a proxy for volume
Some questions/goals:
summary
outliers
prediction
interpretation of coefficients
linear
gaussian errors
