We use Cressie's goodness of fit statistic which allows for number of pairs
and other factors in semi-veriogram fitting. You can find a paper of his in
Methematical Geology around 1992, or in his book. It is also illustrated in our
free tutorial material at www.kriging.com

Hi,
Im working on variogram modelling and in the majority of cases only R2 is
available to evaluate the best-fit values, but in cases of non-linear
functions, it is very criticized.
Are there other standard methods to evaluate the goodness of a fit of a
non-linear function (for example asymptotic confidence intervals) and how to
calculate them, considering that the majority of geostatistical software do not
perform any alternative coefficient?
Thank you
Andrea
