EstimatedVariogramModel
EstimatedVariogramModel[{loc1->val1,loc2->val2,…}] estimates the best variogram function from values vali given at locations loci.
EstimatedVariogramModel[{loc1,loc2,…}->{val1,val2,…}] generates the same result.
EstimatedVariogramModel[…,"model"] estimates the best parameters of the variogram function specified by "model".
EstimatedVariogramModel[…,{"model",params}] estimates the non-numeric parameters in params.
