I have two time-series with different window observation. I have values for
the first one in [0, T] and for the second one in [t1, T] where 0 < t1 < T.
So, they match in a little window [t1, T]. I have an ARIMA model including
two series and I would like to rebuild the second one to the no observed
period, I mean to the period [0, t1]. How could I do that with Gretl?
You can reverse the order of the data and then you can do normal forecasting.
To see how to reverse the order, look at the user's guide, section 13.1
