Dependence Modelling using GARCH, EGARCH, and Copula Models:

open access: yesAsia Proceedings of Social Sciences, 2018
Copula become a popular tool to measure the dependency between financial data due to its ability to capture the non-normal distributions. Hence, this paper will inspect the impact of input models towards the parameter estimation of marginal and copula models for KLCI and FBMHS returns series by considering the ARMA-GARCH model and the ARMA-EGARCH model.

Evaluating exponential GARCH models [PDF]

open access: yes
In this paper, a unified framework for testing the adequancy of an estimated EGARCH model is presented. The tests are Lagrange multiplier or Lagrange multiplier type tests and include testing an EGARCH model against a higher-order one and testing ...

Spatial and spatiotemporal volatility models: A review

open access: yesJournal of Economic Surveys, Volume 39, Issue 3, Page 1037-1091, July 2025.
Abstract Spatial and spatiotemporal volatility models are a class of models designed to capture spatial dependence in the volatility of spatial and spatiotemporal data. Spatial dependence in the volatility may arise due to spatial spillovers among locations; that is, in the case of positive spatial dependence, if two locations are in close proximity ...

Modelling Volatility Cycles: The MF2‐GARCH Model

open access: yesJournal of Applied Econometrics, Volume 40, Issue 4, Page 438-454, June/July 2025.
ABSTRACT We propose a novel multiplicative factor multi‐frequency GARCH (MF2‐GARCH) model, which exploits the empirical fact that the daily standardized forecast errors of one‐component GARCH models are predictable by a moving average of past standardized forecast errors.

International Evidence on GFC-robust Forecasts for Risk Management under the Basel Accord [PDF]

open access: yes
A risk management strategy that is designed to be robust to the Global Financial Crisis (GFC), in the sense of selecting a Value-at-Risk (VaR) forecast that combines the forecasts of different VaR models, was proposed in McAleer et al. (2010c).

Modeling the Interactions between Volatility and Returns using EGARCH‐M

open access: yesJournal of Time Series Analysis, 2018
An EGARCH‐M model, in which the logarithm of scale is driven by the score of the conditional distribution, is shown to be theoretically tractable as well as practically useful. A two‐component extension makes it possible to distinguish between the short‐ and long‐run effects of returns on volatility, and the resulting short‐ and long‐run volatility ...
