Which command did you use for your estimation? If it was non-linear, -nl-?
Show us what you typed and what the reply was...

Subject: st: computation of R-squared with a non-linear model
Dear statalisters,
I estimate a weighted non-linear model of the following form:
y^0.5 = (a1 + a2*X)^0.5 weighted by some other variable z.
Stata reports an adjusted R-squared of 1.000. I suspect this is not
correct. How can compute the correct adjusted R-squared using
untransformed variables?
Best regards,
Marcel Spijkerman
