## Getting Started: VARIOGRAM Procedure

PROC VARIOGRAM uses your data to compute the empirical semivariogram. This computation refers to the steps you take to derive
the empirical semivariance from the data, and then to produce the corresponding semivariogram plot.

You can proceed further with the semivariogram analysis if the data are free of systematic trends. In that case, you can use
the empirical outcome to determine a theoretical semivariogram model by using the automated methods provided by the VARIOGRAM
procedure. The model characterizes the type of theoretical semivariance function you use to describe spatial dependence in
your data set.
