Dear all,

I can't understand what's going on.. I have panel data and when i run BE in stata, individual-invariant regressor is not dropping out. I actually want to use a FE model with the individual-invariant variable and i used between estimator to check the result.. My individual-invariant regressor is tax rate which is the same for each company (and changes every one or three years). I have only one regressor (taxrate) and my depvariable and i haven't add time variable in model due to collinearity with rate.

Thank you
