st: test equality of coefficients from 2 regressions

["Botelho, Delane" <delane.botelho@marshall.usc.edu>]

Hi

I ran 2 regressions (using regress), using the same variables, only changing
the observations. Now I have to test if the 2 coefficients of the same
variable are equal.

I only know how to do this when the coefficients are in the same regression,
or in multiple equations as in mlogit or sureg.

How to test the 2 coefficients in 2 regressions?

Thanks

Delane
