st: how to include aweight variable in xtreg

[Yinghui Li <yinghul@uci.edu>]

Dear Statalisters,

I have a question about  xtreg and need your help!

I used xtreg to  generate a linear regression model with random effect,but
I also want to set a variable as aweight. However xtreg doesn't accept aweight.

-------------------------------------------
* Add facility as random effects *
encode fac_id, gen( n_fac_id );

xtreg y x1 x2 x3, re i( n_fac_id );
-----------------------------------------

Now there is another variable ave_height which is average height of 
people in each facility, I want
 to set it as weight. According to WEIGHT  in Stata, it should be 
aweight. But xtreg only allows
iweights, fweights, and pweights ,it doesn't accept aweight.

Could you please tell me how to do it or do you know if there is any 
other method to do the similar
thing which wants to  generate a linear regression model, with random 
effect, with weighted variable?

Many thanks in advance! I am looking forward to your reply!

Yinghui
