That is, the coefficient of Y(t-1) is 1, implying the presence of a unit root. If not rejected, the series is taken to be non-stationary. WebFor instance, MA(2) uses the residuals from time t-1 and t-2 to predict the value at time t. This can be viewed as the local trend of the time series. We often write (2, 1, 2) to mean an ARIMA model with components AR(2), I(1), and MA(2).
