Recall that the goal of this example is spatial prediction. In particular, you would like to produce a contour map or surface plot on a regular grid of predicted values based on ordinary kriging.

PROC VARIOGRAM computes the sample, or experimental semivariogram. Prediction of the spatial process at unsampled locations by techniques such as ordinary kriging requires a theoretical semivariogram ...
