I am working on a dataset using empirical bayesian kriging . EDA suggests using Log Empirical trasformation and a K-Bessel detrended semivariogram type. Without further adjustment, I achieved the "best" results (concerning error statistics) when using a smooth circular neighborhood type.
I am now trying to give my results more significance, especially concerning the spatial range of the prediction, by using a appropriate search radius.
The only quote concerning this issue I could find so far is in: Sumner, M. E. (1999): Handbook of soil science, and says: "the search radius should not exceed the range of the semivariogram, and is typically less than ½ the range”.
Is this a good starting point or are there other suggestions?
