Hi, In addition to the list provided by Paul, I would like to add Geostatistics for Environmental Scientists, 2nd Edition Richard Webster, Margaret A. Oliver I have used it in courses for agricultural and environmental engineers and it worked well. I think that the balance between mathematical

Hi Pilar, I think this list appropriate :). What would be a good idea is to get a book that describes kriging, some standard books are: Chilès, J. & Delfiner, P. Geostatistics: Modeling Spatial Uncertainty John Wiley & Sons, New York, 1999 Christensen, R. Plane Answers to Complex Questions: T

Dear all, I'm trying to estimate the variance of a global abundance estimation computed by kriging interpolation and I am stuck. One can easily retrieve the variance at each prediction location (either using the package gstat, geoR or automap) using expressions similar to: >kriging_object$kri
