[ai-geostats] equivalence of mean and var

It was previously mentioned that a common approach is to subdivide populations into those of equal mean and variance so that stationarity is obeyed. What do you suggest as tests for determining equivalence of mean and variance prior to spatial analysis? Thanks, Randy. * By using the

[ai-geostats] comparing variograms?

Dear ai-geostats Members, Are there appropriate statistical tests for determining whether empirical variograms are statistically different (maybe something akin to a Kolmogorov-Smirnoff or chi-square test)? Is there a test for comparing variogram model parameters? If not, why? If so, what
