608AI-GEOSTATS: Variogram-parameter covariance matrix

      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.
