Multimodality and the GARCH Likelihood [PDF]

open access: yes
We investigate several aspects of GARCH models which are relevant for empirical applications. In particular, we note that the inclusion of a dummy variable as regressor can lead to multimodality in the GARCH likelihood.

Exact Maximum Likelihood estimation for the BL-GARCH model under elliptical distributed innovations [PDF]

open access: yes
In this paper, we discuss the class of Bilinear GATRCH (BL-GARCH) models which are capable of capturing simultaneously two key properties of non-linear time series : volatility clustering and leverage effects. It has been observed often that the marginal

Crisis, Value at Risk, and Conditional Extreme Value Theory via Garch-Jump Model

open access: yes, 2010
This study develops a new conditional extreme value theory-based model (EVT) combined with the GARCH-Jump model to forecast extreme risks. This paper utilizes the GARCH-Jump model to asymmetrically feed back the past realization of jump innovation to the

The Continuous Limit of GARCH Processess [PDF]

open access: yes
Contrary to popular belief, the diffusion limit of a GARCH variance process is not a diffusion model unless one makes a very specific assumption that cannot be generalized.

Forecasting Airtel Stock Prices Through Decomposition and Integration: A Novel VMD-GARCH-LSTM Framework

open access: yesInternational Journal of Mathematics and Mathematical Sciences
Stock price forecasting is complex due to the nonlinear and nonstationary nature of financial time series. This study proposes a hybrid variational mode decomposition (VMD)–generalized autoregressive conditional heteroskedasticity (GARCH)–long short-term

Asymptotic Theory for a Vector ARMA-GARCH Model, [PDF]

open access: yes
This paper investigates the asymptotic theory for a vector ARMA-GARCH model. The conditions for the strict stationarity, ergodicity, and the higherorder moments of the model are established.

From Discrete to Continuous: Modeling Volatility of the Istanbul Stock Exchange Market with GARCH and COGARCH [PDF]

open access: yes
The objective of this paper is to model the volatility of Istanbul Stock Exchange market, ISE100 Index by ARMA and GARCH models and then take a step further into the analysis from discrete modeling to continuous modeling.

Selection of the Informative Base in ARMA-GARCH Models [PDF]

open access: yes
In this paper we consider the selection of the information set in ARMA-GARCH models using the methodology proposed in Muñoz et al. (2001) based on ideas of Phillips (1996). To that end, we analyse the performance of some selection criteria asymptotically
