[Gretl-users] Newbie questions about using systems in Gretl

Hello! Please forgive me if the following questions are a little bit "stupid", but as I mentioned, I'm a newbie... My aim is to build up a little macro-model like the "klein.inp", using ols estimations, and to do forecasts with it. Some questions arise hereby: 1. In the command reference, page 51 (A4-Version) about using systems it is mentioned that identities are needed if FIML estimation is used. But also with ols or other estimations the system has to know how to create the forecast values of derived variables which are not estimated inside the system. Did I miss anything in the reference? And I guess that also with ols-estimation I have to declare the endogenous variables? 2. Which command is necessary if I want the system to do forecasts for the system as a whole? In the graphic interface there is the possibility to select only one estimated variable, but as you know the clue of using systems is all variables are estimated simultaneous in mutual dependency...
