The volatility function of the ARMA innovations is shown to be the square of the corresponding GARCH volatility function. The prediction of GARCH squares is facilitated by the ARMA structure and predictive intervals are considered. Further, the developments suggest families of volatile ARMA processes.}, type={Artykuły / Articles}, title={Volatile ARMA Modelling of GARCH Squares}, URL={http://journals.pan.pl/Content/103812/PDF-MASTER/mainFile.pdf}, doi={10.24425/cejeme.2010.119328}, keywords={ARCH, ARMA, GARCH, prediction, time series, volatility}, }
