Some well-known special cases arise naturally or are mathematically equivalent to other popular forecasting models. For example: • An ARIMA(0, 1, 0) model (or I(1) model) is given by — which is simply a random walk. • An ARIMA(0, 1, 0) with a constant, given by — which is a random walk with drift. WebA seasonal random walk model is a special case of an ARIMA model in which there is one order of seasonal differencing, a constant term, and no other parameters--i.e., an "ARIMA (0,0,0)x (0,1,0) model with constant." To specify a seasonal random walk model in Statgraphics, choose ARIMA as the model type and use the following settings: WebFor an ARIMA model, the number of AR lags, number of differences, and number of MA lags is called the model order or just order.
