Subject: Re: st: constant term in xtreg, fe

There's a Stata FAQ about this.  My recollection is that the program comes 
up with some kind of weighted average of the coefficients on the case 
specific intercepts.

Dear Statalisters:
I am running panel model, and have something unclear about the output 
produced by Stata. According to Stata manul, xtreg with fe option is 
estimated using OLS demeaned equation. WHat I am unclear about is how is 
the _cons computed, is it first to get fixed effect estimates, then get 
back to intercept like:
intercept = y_grand-mean -  (x_grand-mean)'B(fix_effect_estimates)? and 
its standard error therein?
