Thanks for quick responses. I re-testes it and found that "adding observations" windows occurs if the estimated AR is without a constant. For example,
open bjg.gdt smpl ; -10 model1 <- arima 1 0 1; g --nc Then, turn to GUI of model1 to do the forecasts. ps: My apology, I will create a new thread next time Yi-Nung Artur T. <ate...@posteo.de> 於 2023年5月1日 週一 下午9:29寫道： > Am 01.05.23 um 13:23 schrieb Sven Schreiber: > > Next time, please start a new thread for a new topic instead of replying > > to another message.
