Hello, I am trying to compare the zscores of using various kriging methods with inverse distance weighting.
When I run crossval_idw <- krige.cv(Prec00hr~1, DataCoordhr, nfold=2) I get all NA's for the zscore. As the residual is a valid number, I am assuming that the standard deviation is not being calculated properly. However, I can calculate the standard deviation of the residual: sd(crossval_idw$residual) As an aside, I also get all NA's for the variances even though, I also can calculate the variances separately. var(crossval_idw$residual) Any ideas? Thank you for your help, Cara [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
