Where are coefficients for global polynomial interpolation?

After producing a geostatistical layer using global polynomial interpolation using, for example, the Geostatistical Wizard, how can I access the actual coefficients for the n'th order polynomial that the Wizard produces. Clearly, these coefficients are stored in the ArcMap geostatistical layer, but I can't find any method (the generic sense) to access them. In addition, I can't find the format of the layer file in order to access them with a binary file reader.

I notice that for some kinds of regressions in Spatial Analyst, the coefficients can be outputted to a file when using Arcpy. Howevr, I have not found any facility to get at the coefficients produced for global polynomial interpolation in Geostatistical Wizard. The only information on the polynomial that the Wizard outputs at the end is the order of the polynomial which in actually an input.

Does anyone know how to do this?
