The GARCH(1,1) model and its extensions Hanno Reuvers

WebA generally accepted notation for a GARCH model is to specify the GARCH () function with the p and q parameters GARCH (p, q); for example GARCH (1, 1) would be a first order GARCH model. A GARCH model subsumes ARCH models, where a GARCH (0, q) is equivalent to an ARCH (q) model.
