The standard deviation (SD) is reported here because it was required to calculate CV_Traditional.

- indicates that the semivariogram model did not reach its sill, which prevented sill, range, and nugget values from being accurately estimated.

Sample size required to estimate to with 10% of the spatial mean with 90% confidence.
