RESENDING!  

 

That is correct, my Obtuse package does not do Kriging. When I wrote the
package, I was more interested in distance-based interpolation methods,
working in any number of dimensions. And the threshold to master Kriging was
higher than my patience and competence. Is there any other Mathematica code
for Kriging anywhere? Or can anyone recommend a good introduction?

 

Best regards

 

Ingolf Dahl

Depending on the nature of the OP's problem, Kriging interpolation might be
appropriate.

I don't know much about this stuff, but insofar as I can tell, Ingolf Dahl's
Obtuse package

does not do Kriging. (I might be wrong here).
