st: absorbing a catagorical variable in panel data regression

["Christer Thrane" <ch-thran@online.no>]

Hi,

My observations are person-years and my aim is to see how various 
time-constant and time varying variables affect annual earnings.

In this respect I want to control for the variable occupation, which has 200 
values (i.e., occupation titles). In a cross-sectional regression, I would 
use -areg- with the "absorb" option (I don't need 199 coefficients, but only 
the F-test from ther inclusion), but I have not found a similar command 
for -xtreg- or -gee-.

Any pointers are appreciated! Thanks in advance!

Christer
