Implement and fit a variety of short-memory (SM) and long-memory
(LM) models from a very broad family of exponential generalized autoregressive
conditional heteroskedasticity (EGARCH) models, such as a MEGARCH (modified
EGARCH), FIEGARCH (fractionally integrated EGARCH), FIMLog-GARCH (fractionally
integrated modulus Log-GARCH), and more. The FIMLog-GARCH as part of the
EGARCH family is discussed in Feng et al. (2023)
<https://econpapers.repec.org/paper/pdnciepap/156.htm>. For convenience and
the purpose of comparison, a variety of other popular SM and LM GARCH-type
models, like an APARCH model, a fractionally integrated
APARCH (FIAPARCH) model, standard GARCH and fractionally integrated GARCH
(FIGARCH) models, GJR-GARCH and FIGJR-GARCH models, TGARCH and FITGARCH
models, are implemented as well as dual models with simultaneous modelling of
the mean, including dual long-memory models with a fractionally integrated
autoregressive moving average (FARIMA) model in the mean and a long-memory
model in the variance, and semiparametric volatility model extensions.
Parametric models and parametric model parts are fitted through
quasi-maximum-likelihood estimation.
Furthermore, common forecasting and backtesting functions for value-at-risk
(VaR) and expected shortfall (ES) based on the package's models are provided.
