Hi, for testing purposes I stumbled over the question of gretl's ways of running a fixed effects (FE) panel regression when the dependent variable is not time-varying. Example: <hansl> open abdata panel IND const INDOUTPT # FE per default </hansl> I would have thought that gretl either refuses to execute this, or perhaps would drop the fixed effects, or something. But it reports some -arguably strange- output wihtout explicit indication of a problem. (Is this perhaps due to the panel being unbalanced?) Thanks for any clarification sven
