[Gretl-users] Forecasting

Hi, I'm a new GRETL user's and I have problems with forecasting. I estimated a regression with OLS and i like to do a forecast out of sample. Is it possible? When i try Analysis, Forecast, i receive the message: "there are no observation available for forecasting out of sample. If you wish, you can add observation, or you can shorten the sample range over which the model is estimated." I would like to do a real forecast out of sample, how can i do? Thanks, Guido ___________________________________ L'email della prossima generazione? Puoi averla con la nuova Yahoo! Mail: http://it.docs.yahoo.com/nowyoucan.html
