I am looking for functions in arcobject to fit semivariogram. I mean I can get the value of  lag, nugget,sill to description the model through calling the function. it is not in the "IGeoAnalysisSemiVariogram" interface.I would appreciate it very much if any one can tell me the name space it belongs to. whether I have to write the code by myself.
