Dear All,
I would like to ask you for help with Gretl software. I am writing you
with an problem which I face during making forecast / prediction. I
estimated econometric model with one depended variable and four
explanatory variables. Method of estimating was OLS or Cochrane - Orcutt
(both with same result). When I try to make a forecast into the future
(*and Yes, I added new observations into the new data set*) I am unable
to forecast into the future.
*Gretl notices:* There are no observations available for forecasting out
of sample. If you wish, you can add observations (Data menu, Edit
data), or you can shorten the sample range over which the model is
estimated (Sample menu).
The other replies already answered the main problem I think, but this
error message would seem a little confusing. Is this the actual message
that you get, i.e. are you working in English, or have you translated it
back perhaps?
cheers,
sven
