Dear list members: Do you expect that the uncertainty related to estimating variogram parameters have a strong effect on spatial prediction via ordinary kriging? It is my impression that usually the analist disregard this source of variance and proceeds as if these parameters from the variogram were known. This might be justified since normally the sample size (pairs of observations) is quite high when fitting the variogram via weighted least squares, for instance. Any opinion on this and/or references would be much welcome. Thanks Ruben Roa
