WebFor ARIMA models with differencing, the differenced series follows a zero-mean ARMA model. If an xreg term is included, a linear regression (with a constant term if include.mean is true and there is no differencing) is fitted with an ARMA model for the error term.

WebDespite the buildup, we’ll actually see that an ARIMA model is just an ARMA model, with a preprocessing step handled by the model rather than the user. Let’s start with the equation for an ARIMA(1,1,0) model. The (1,1,0) means that we have one autoregressive lag, we difference our data once, and we have no moving average terms.
