Estimation of Stochastic Volatility Models with Heavy Tails and Serial Dependence

Abstract: Financial time series often exhibit properties that depart from the usual assumptions of serial independence and normality. These include volatility clustering, heavy-tailedness and serial dependence. A voluminous literature on different approaches for modeling these empirical regularities has emerged in the last decade. In this paper we review the estimation of a variety of highly flexible stochastic volatility models, and introduce some efficient algorithms based on recent advances in state space simulation … Show more

“…On the other hand, if we were to use pure Gibbs sampling to estimate the SV model with Student-t distributed errors then we would be forced to follow Chan and Hsiao (2013) and convert the model into a conditionally Gaussian state space model by defining the measurement error in (2.1) as ε t = λ −1/2 t e t where e t ∼ N (0, 1), λ t ∼ IG (v/2, v/2) and has a closed form conditional posterior. We would then follow the steps in Chan and Hsiao (2013) and sample from the augmented posterior,…”
