Hi, I'm 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
