I'm trying to forecast the ARMA (1,1) process out of sample (X t+1), but it shows a message that this cannot be done (only in sample fcast). I tried everything, including some commands - fcast, --out-of-sample, dataset addobs 1, --dynamic. I also tried to ad new observations via the graphical interface, to generate forecast, but, without success either. There is something that I'm not doing right. Can anyone please give a thought, what goes wrong? Maybe my commands are inadequate. Tanks in advance, for any valuable help. My best, Fabio ps. I know I can use the coeficients in spreadsheet to generate the fcast, but Im trying to figure out whats is happening. -------------- next part -------------- An HTML attachment was scrubbed...

I was unable to pick a hint looking at the past discussions. It seems to me - sometimes - yahoo_get.gfn does not recognize the "right" ticker [tested only on Linux] this is the gretl output ----------------------------------------------------------------------- --- gretl versione 2016a Sessione corrente: 2016-05-02 19:02 # Apro un set di 100 giornate con ? nulldata 100 Periodicit?: 1, oss. max.: 100 Intervallo delle osservazioni: 1-100 # 5 rilevazioni settimanali che iniziano il 1 gennaio 2015 e indico che ? una serie temporale ? setobs 5 2016-01-01 --time-series Campione completo dei dati: 2016-01-01 - 2016-05-19 (n = 100) # chiama la funzione yahoo_get ? include yahoo_get.gfn /home/guido/.gretl/functions/yahoo_get.gfn # scarico i titoli ? loop foreach i FP.PA UL.PA FR.PA > A=yahoo_full("$i") > endloop ?

Clearly, the error should be handled better, but I don't quite know what to do.
