      hello all,
      i have a multiple regression model from ln-transformed data and want to
      krige the residuals. how do i get backtransformed residuals from
      ln-transfortmed data ? when i backtransform ln-residuals negative ln-values
      are just interpreted as positive values below 1,0. is it possible to get
      residuals by substracting (backtransformed) predicted values (regression
      model) from the original values?

      hope you can help me
      greetings
      Lenz
