Semivariogram Models• It is a mathematical expression that results from
curve fitting a function to the experimental variogram.
• Models are used to determine variogram parametersthat are necessary in both estimation (kriging) and conditional simulation procedures.
• Model variograms can be classified according to the presence or absence of sill into two groups:
• Models with sill (transition models)• Models without sill (drift or trend models)
