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...
