"Webduced by (Box and Pierce 1970) is perhaps a base for many time series forecasting solution. This model is a bundle of two variants: the autoregression(AR) and the moving aver-age (MA) models. One limitation is it only looks back of the dependent variable but fails to capture an unusual change of a pattern. " - Box and pierce 1970
