Hi guys!

I have a problem with Gretl panel fixed effects model. I created dummy variables to control for fixed effects (it was a proper way), but Gretl leaves these dummies out. To represent 4 categoeries I used 3 dummies to avoid perfect multicolinearity. In the end I habe a biased result because of the omitted dummies. Is there a solution for the problem?

Thanks a lot in advance!
