cross validation gstat
Hi list, A quick question regarding n-fold validation... I've seen several papers suggest the LOOCV is too optimistic. Is n-fold closer to a "true" validation? I am assuming that it uses the variogram that is constructed using ALL data, so my assumption is that the variogram is not re-fit for each n-fold before estimation...
