Have you had a look at -hausman-? In cross-sectional models, -suest- would

we are estimating the following models (same specification, but different
estimation method) on two different sub-samples ( A and B).
A) xtreg y x1 x2 x3 x4, fe

Is there a command to test whether (b1+b2+b3) in A=( b1+b2+b3) in B ?
thank you in advance
best regards
Francesco
