Lecture 5a: ARCH Models - Miami University
www.fsb.miamioh.edu• The generalized ARCH or GARCH model is a parsimonious alternative to an ARCH(p) model. It is given by σ2 t = ω + αr2 t 1 + βσ 2 t 1 (14) where the ARCH term is r2 t 1 and the GARCH term is σ 2 t 1. • In general, a GARCH(p,q) model includes p ARCH terms and q GARCH terms. 16
