An asymmetric GARCH model assumes that the response of the conditional variance (volatility) to shocks depends on both the intensity and sign …
WebJul 14, 2006 · Abstract. We develop univariate regime-switching GARCH (RS-GARCH) models wherein the conditional variance switches in time from one GARCH process to another. The switching is governed by a time-varying probability, specified as a function of past information. We provide sufficient conditions for stationarity and existence of … http://article.sapub.org/10.5923.j.ajms.20240805.08.html
