WebThe difference operation in ARIMA models is denoted by the I letter. In ARIMA, I stands for I ntegrated. Differencing is applied by ARIMA models before the AR and the MA terms are brought into play. The order of differencing is denoted by the d parameter in the ARIMA (p,d,q) model specification.

WebNo ARIMA(p,0,q) model will allow for a trend because the model is stationary. If you really want to include a trend, use ARIMA(p,1,q) with a drift term, or ARIMA(p,2,q). The fact that auto.arima() is suggesting 0 differences would usually indicate there is no clear trend. The help file for arima() shows that the intercept is actually the mean.

WebThis is the same as finding the MA representation of an ARMA (p,q). By reversing the role of ar and ma in the function arguments, the returned result is the AR representation of an ARMA (p,q), i.e. ma_representation = arma_impulse_response (ar, ma, leads=100) ar_representation = arma_impulse_response (ma, ar, leads=100)
