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… WebApr 13, 2024 · The GARCH model is one of the most influential models for characterizing and predicting fluctuations in economic and financial studies.
