The generalized t distribution Our model builds on the GARCH model of Engle (1982) and Bollerslev (1986). 2 Within this class of models, it is well known that residuals are non-normal. This result has led to the introduction of fat-tailed distributions.

WebJun 11, 2024 · Moreover, several papers have demonstrated that the performance of option valuation models with conditional heteroskedasticity can be further improved by including a so-called leverage parameter ( Nandi, 1998; Heston and Nandi, 2000; Chernov and Ghysels, 2000; Christoffersen and Jacobs, 2004 ). The combination Webdefinition of the word “crashes”, associating it solely with the conditional skewness of the return distribution; we are not in the business of forecasting negative expected returns. This usage follows Bates (1991, 1997), who also interprets conditional skewness—in his case, inferred from options prices—as a measure of crash expectations.
