Hi,
Variowin/equation questions:
I have fitted models using variowin and am now trying to plot them in
other graphics programs. Vario2D produces a file that I can use to plot the
experimental variograms, but in the modeling I get an equation like:
gamma(h) = 14.2 + 6.399 Sph. 169.66(h)
I am

Judging the fit of a model cannot be done from the
summary statisics. See my 1986 paper "The Art of Cross
Validation" (full reference at

Better to use something like Noel Cressie's goodness
of fit statistic which tests the semi-var
