st: Nonlinear LR Test in SUR context

[Gernot Wagner <gwagner@fas.harvard.edu>]

Hello,

How do I implement a nonlinear likelihood-ratio test in a SUR context? 
If it was linear, I would use "constraint" to estimate my restricted 
regression, but that does not work with a nonlinear equation. Is there 
an equivalent nonlinear command?

Many thanks,
Gernot Wagner
