Not sure the quality of the light, but I've had that issue with Proc Model
as well. I believe the negative R^2 is a result of it being non-linear.
Been a little while so I don't remember the specifics of what I did about
it, I think just looked at MSE's to compare models instead of R^2s.

Subject: R-Square Negaive?
I'm using MODEL Procedure,but I'm not familiar to this Procedure and
surprised to NEGATIVE R-Square.
Exactly I'v gotten this outpout:
The MODEL Procedure
Nonlinear OLS Summary of Residual Errors
Equation Model Error SSE MSE Root MSE R-Square
amt2 4 2614 8140.1 3.1140 1.7647 -0.2179
Can somebady shed light on this issue?
