Hi, George:
I think that you should use testnl instead.

Subject: st: How to test ratio of coefficients
Hi,
I have following regression:
reg y x1 x2 x3 x4 x1Xx3 x1Xx4 x2Xx3 x2Xx4
I would like to compare ratio of coefficients on x1Xx3 / x1Xx4 with the
following ratio: x2Xx3 / x2Xx4.
I try to use the following commend:
test x1Xx3 / x1Xx4 = x2Xx3 / x2Xx4
However, I got the result stated “not possible with test”. Are there other
ways to solve the problem?
Any suggestion is greatly appreciated.
Best,
George
