Model Variogram

Select menu: Stats | Spatial Analysis| Model Variogram

Fits various models to the experimental variogram. Models must be authorized in the sense that they cannot give rise to negative variances when data are combined. If the Krige dialog is open, the model and its parameters in that menu will be set to those from the
model just fitted.

After you have imported your data, from the menu select
Stats | Spatial Analysis | Model Variogram.
Fill in the fields as required then click Run.

You can set additional Options then after running, you can save the results by clicking Save.
