Re: st: value labels in output regression model
I am using a pannel data. I want to know the difference between xtreg and
xtgls. I have used xtreg for fixed effect and random effect models. due to
the problem of heteroscadisticity i think gls is a better estimator. I want
to know whether 'xtreg' command uses gls method for its estimation for fixed
and random effect.
