Re: Cross validation



No, but I can see there is a need for this.

Writing this is not a straightforward extension to krige.cv; I'd rather
extend predict.gstat -- you'd like to extend it to cokriging with
arbitratrily many variables.

One catch is that it is not really straightforward whether secondary
variables should be omitted at prediction locations or not; also, whether
they should be cross validated as well.

I you don't see it appear (or announce), keep reminding me this
is missing; right now I have too little time to accomplish this.

Hello gstat-R users,
 
In R the krige.cv function does cross validation for kriging. My question is this: there is any function to do cross validation for cokriging or is possible somehow to accomplish the cross validation for cokriging?
 
Thanks in advance
