Re: st: how to access coefficients for each observation in panel data with fixed effects

[Amy Hieter <amy.hieter@gmail.com>]

My apologies I was not clear.

I am trying to get the coefficient of   var1    for each observation
in the dataset, not just for the average observation across the data
set that I obtain from the -xtreg- output.

For example, I believe I can access the fixed effects for each county by:

predict u, u
replace u = u + _b[_cons]

I want to be able to do something similar for each variable in the model.

I took a look at he help on post estimation for -xtreg-   but I did
not see anything that would provide these values. Though perhaps
(likely) I am misunderstanding the help.

Hopefully this made more sense.
