Exponential, generalized, autoregressive, conditional heteroscedasticity models for volatility clustering

If positive and negative shocks of equal magnitude asymmetrically contribute to volatility, then you can model the innovations process using an EGARCH model and include leverage effects. For details on how to model volatility clustering using an EGARCH model, see egarch.
