As i said in my message, I wanted to know if by imposing equality between coef I can get test results equivalent to the ones obtained with a chow test (for 2 categories). Probably the name is no more chow, but it has the same meaning of this test. the only difference is related to the no of cateories employed.
Anyway thanks, I'm going to add this question:
is the tes result enough to allow me to run separate reg (one for each category)??

thanks
Ok I am confused. When you say

b1=b2=b3=b4=b5

That makes me think that you want to test the equality of the coefficients for variables x1, x2, x3, etc. Do you mean instead that you want to test the equality of coefficients across populations for population 1, population 2, etc? If so, check out the FAQs at
