I have to use ordinary cokriging (variables are precipitations and elevation).

I build an automatic model (in model builder) to perform interpolation.

However, when I build the .xml file (reference file) with the geostatistical wizard why the last equation noted when we fit variograms and Cov. aren�??t the same when we open again the model in the method properties after computation?

I don�??t understand why parameters of the first variable (first variogram) are automatically applied to the model (nugget and partial sill), other parameters are the same.

It�??s not possible to have specific parameters for each variable and so each variogram and to keep them as we want (in the model equation under the variogram) ?

Maybe there is something I don't understand with the use of several fit-models .....

For examples:

Manual fitting and Reopening of the method properties after computation: see model equations

The first graphic is pulling Nugget[1][1] and Partial Sill[1][1] from all models. Graphic 2 is pulling Nugget[0][0] and Partial Sill[0][0]. The cross-covariance (not pictured) between elevation and precipitation is from Nugget[0][1] and Partial Sill[0][1].

I'm not seeing any problems with the graphics you posted. Can you try to clarify your question?
