## Description

A valid semivariogram could not be computed using the current settings for the number of lags and lag size. These values can be altered in ArcMap 10.3 or earlier.

## Solution

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