[Gretl-users] Forecasting

[guido mastrolilli]

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
