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