st: Postestimation after NL Regression

Subject   st: Postestimation after NL Regression

I'm sure I'm making some sort of basic mistake, but I can't figure out how
to run a postestimation test after computing a nonlinear regression.

For instance, if my nl model is:

nl (outcome = exp({b0} + {b1}*var1 + {b2}*var2 + {b3}*var3 + {b4}*var4))

How do I test that b1 and b2 are greater than 0?

The help nl postestimation indicates that I can use the test command, but I
can't figure out how to format it correctly.

Any help would be greatly appreciated.

Scott
