st: Xtreg is dropping dummy variable for OECD countries.

["Steffen H. Gr�ning" <(removed)>]

Hi everybody,

When running a regression on my panel data for per capita growth, i
would like to include a dummy variable for the OECD Countries. Once
using a fixed effects model however, it is dropped.
May be it is just too late to work, but could somebody point out why
Stata does that?

Any pointer appreciated.
Thanks.

Steffen.
