For example, to create an EGARCH(1,2) model containing unknown parameter values, enter: Mdl = egarch(1,2);To impose equality constraints on parameter values during estimation, set the appropriate property values using dot notation. P— GARCH polynomial degree nonnegative integer Q— ARCH polyno...
GJR-ARCH model & EGARCH model 无情小超超 我只想要一些好的风景12 人赞同了该文章 背景:GARCH模型相对于ARCH模型来说,it can capture smooth volatility, clustering, fat tails; 但是GARCH模型在对于昨天的shock是正还是负上的反馈是一致的;但往往市场对于negative volatility会更敏感:也就是large negative...
