      Hi:

      We had participated in AI-GEOSTATS SIC 2004 exercise in the past September.
      I think that several techniques (Kriging, regression, etc.) may have been
      used by different participants. It will be illuminating to read the final
      report of SIC 2004 when available.

      (We had used an interpolant/estimator similar to "IDW" and "nonparametric
      regression".)
