[HTML][HTML] Shifts in volatility driven by large stock market shocks

Y Dendramis, G Kapetanios, E Tzavalis - Journal of Economic Dynamics …, 2015 - Elsevier
This paper presents an extension of the stochastic volatility model which allows for level
shifts in volatility of stock market returns, known as structural breaks. These shifts are …

Improving variance forecasts: The role of Realized Variance features

I Papantonis, L Rompolis, E Tzavalis - International Journal of Forecasting, 2023 - Elsevier
In this paper, we effectively extend the Realized-EGARCH (R-EGARCH) framework by
allowing the conditional variance process to incorporate exogenous variates related to …

Do realized higher moments have information content?-VaR forecasting based on the realized GARCH-RSRK model

T Wang, F Liang, Z Huang, H Yan - Economic Modelling, 2022 - Elsevier
In this paper, we develop a new model, the Realized GARCH-RSRK, to determine the time-
varying distribution of financial returns with realized higher moments. Based on Gram …

Polynomial adjusted Student-t densities for modeling asset returns

Á León, TM Ñíguez - The European Journal of Finance, 2022 - Taylor & Francis
We present a polynomial expansion of the standardized Student-t distribution. Our density,
obtained through the polynomial adjusted method in Bagnato, Potí, and Zoia (2015.“The …

Volatility specifications versus probability distributions in VaR forecasting

L Garcia‐Jorcano, A Novales - Journal of Forecasting, 2021 - Wiley Online Library
We provide evidence suggesting that the assumption on the probability distribution for return
innovations is more influential for value‐at‐risk (VaR) performance than the conditional …

Two-sided Lindley distribution with inference and applications

E Altun - Journal of the Indian Society for Probability and …, 2019 - Springer
We propose a new distribution, called two-sided Lindley distribution. Some of its statistical
properties are derived including the probability and cumulative density functions, moments …

A new generalization of skew-T distribution with volatility models

generalized autoregressive conditional heteroskedasticity (GARCH) models in modelling …

A new approach to Value-at-Risk: GARCH-TSLx model with inference

E Altun - Communications in statistics-simulation and …, 2020 - Taylor & Francis
