WebNov 2, 2024 · As with ARCH, GARCH predicts the future variance and expects that the series is stationary, other than the change in variance, meaning it does not have a trend or seasonal component. How to Configure ARCH and GARCH Models. The configuration for an ARCH model is best understood in the context of ACF and PACF plots of the … WebIn the rst two parts we give a short overview of the known limit theory for the sample ACF of linear processes and of solutions to stochastic recurrence equations (SRE’s), including the squares of GARCH processes. In the third part we concentrate on the limit theory of the sample ACF for stochastic volatility models.

If an autoregressive moving average (ARMA) model is assumed for the error variance, the model is a generalized autoregressive conditional heteroskedasticity (GARCH) model. In that case, the GARCH (p, q) model (where p is the order of the GARCH terms and q is the order of the ARCH terms ), following the notation of the original paper, is given by Generally, when testing for heteroskedasticity in econometric models, the best test is the White t…
