Hi all!

I want to fit a time series with 17376 values by using the arima() function.

If I extract the residuals from the fitted model there are values for the
residuals 1 to 710 but the residuals 711 to 17376 have the value NA.
Does anybody know what the problem could be? Is the function arima()
restricted to a maximum length of the underlying time series?

Besides, is there a better possibility to get the fitted values from an
arima model than using the residuals?

It would be great if somebody could help me!

Thanks a lot in advance...
Cheers,
Katharina
