R-square in ILWIS

aoygeo
Hi, I'm now doing phD in land resources and Environment field.I use ILWIS software to do geostatistics for soil salinity by following ILWIS user guide in chapter11. In the section of fitting variogram by input the number of nugget sill and range by user. Is it ok to test how good is my model using Goodness of fit (R-square) ? is this equation is the same as r-square = 1-sse/sst? becuase I've heard that it can be use to test in the case of Least square fit method but for fit the model in ILWIS we consider by the user, isn't it? ...Thank you in advance for your kind advice and answer...
