Hi all,

I am starting to work with GSTAT under R, and I would like to know whether 
back-transformation (log transformation) of prediction results is possible 
under GSTAT. Any suggestion is welcome. 

Thanks in advance,

 

R can do the back-transform for you, if it's limited to simply calculating
the exponent. This gives you a median-type estimate on the original
scale. If you want an expectation-type estimate on the original
scale, you'd need the lagrange multiplier to do this and gstat does
not provide this as separate information; you'd have to modify it.
