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.
- 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.
