040022 : A valid semivariogram model could not be calculated.

Description

A valid semivariogram model could not be computed using the current settings for the number of lags and/or lag size.

Solution

Adjusting the number of lags may resolve the problem. For small lag sizes, increase the lag size so that more pairs will be used in each lag. For large lag sizes, reduce the lag size so that values for more lags can be calculated.
