Image by the author. In the figure below we show how the ACF and PACF behave for AR, MA, or ARMA processes in the case of an order 1. 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.
