WebBox and Jenkins recommend the differencing approach to achieve stationarity. However, fitting a curve and subtracting the fitted values from the original data can also be used in the context of Box-Jenkins models. Seasonal differencing At the model identification stage, our goal is to detect seasonality, if it exists, and to identify the order ... WebThe Box–Jenkins methodology for ARMA models (dating back to time where computing ressources were scarce) allows one to select the order of an AR ( p p ), MA ( q q) or …
