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… WebDec 6, 2024 · The EGARCH is an asymmetric GARCH model that specifies not only the conditional variance but the logarithm of the conditional volatility. It is widely accepted that EGARCH model gives a better in-sample fit than other types of GARCH models. The exponential GARCH model or EGARCH by Nelson (1991) captures the leverage effect …
WebAutocorrelation in the conditional variance process results in volatility clustering. The GARCH model and its variants model autoregression in the variance series. Leverage effects. The volatility of some time series responds more to large decreases than to large increases. This asymmetric clustering behavior is known as the leverage effect.

WebAbstract. This article develops the dynamic asymmetric GARCH (or DAGARCH) model that generalizes asymmetric GARCH models such as that of Glosten, Jagannathan, and Runkle (GJR), introduces multiple thresholds, and makes the asymmetric effect time dependent.
