Hi Jeph,
Thanks for your reply. I found that both xtmixed and xtrc can do
random coefficients model in Stata. I have an unbalanced firm-year
panel with over 500 firms and about 30-year long time series. I want
to calculate a regression coefficient for each firm. I am not sure
which one of the two methods fits my data better and what are the
difference between them. Any advice?
Thanks.
Lu
