Hi there, Hope somebody can answer a newbie's question. Although it may be ill-conditioned, my question is, how can I compare the result of OLS model and a model by universal kriging (OLS with residuals fitted by variogram)? What I mean is, how can I show kriging the residuals does improve the model? Could the comparison be done in the sense of R^2 of OLS? Or the only way is to do Chi-square test based on difference of log likelihood?
Thanks a lot. Tib
