Dear Statalisters,
If I estimated a regression equation like this,
y=b0hat+b1hat*x1
If I want to get the standard error of (-b0hat/b1hat),
how can I do it?
It seems easy in TSP and LIMDEP, but I don't know how
to get it with STATA? Your help is highly appreciated.
It is easy in Stata, too. See testnl.

Not sure, but since he wants the s.e. I think he wants
