Dear colleagues,
“arima” returns directly the 1-step ahead errors but I am interested in
obtaining other h-step ahead errors for several ARIMA models I have fitted.
Is there any way I can obtain this with R? Any help would be appreciated.
See ?predict.Arima, the predict() method for its output.
Note that arima() returns the fittted innovations: these are not
necessarily the '1-step ahead errors' but estimates of them. (E.g. think
about missing values.)
Sincerely,
Nuno Prista
