I would like to know how to use the coefficients generated by the ARIMA model to predict future values. What formula should be used with the coeffcients to determine the future values.

Hi, the help page for arima() suggests looking at predict.Arima(), so take a look at ?predict.Arima(). You will probably not use the coefficients, but just feed it the output from arima(). And take a look at auto.arima() in the forecast package. HTH Stephan testuser schrieb:> I would like to know how to use the coefficients generated by the ARIMA model > to predict future values.
