Scalable inference for a full multivariate stochastic volatility model

نویسندگان

چکیده

We introduce a multivariate stochastic volatility model that imposes no restrictions on the structure of matrix and treats all its elements as functions latent processes. Inference is achieved via carefully designed feasible scalable MCMC has quadratic, rather than cubic, computational complexity for evaluating normal densities required. illustrate how our can be applied macroeconomic applications through VAR model, comparing it to competing approaches in literature. also demonstrate approach large dataset containing 571 stock daily returns Euro STOXX index.

A Multivariate Stochastic Volatility Model

Anastasios Plataniotis and Petros Dellaportas [email protected] [email protected] Department of Statistics, Athens University of Economics and Business, Greece Summary: We introduce a broad class of multivariate stochastic volatility models where transformed eigenvalues and Givens rotation angles are assumed to be AR(1) processes. This decomposition retains the required positive definite structure of...

The multivariate supOU stochastic volatility model

Using positive semidefinite supOU (superposition of Ornstein-Uhlenbeck type) processes to describe the volatility, we introduce a multivariate stochastic volatility model for financial data which is capable of modelling long range dependence effects. The finiteness of moments and the second order structure of the volatility, the log returns, as well as their “squares” are discussed in detail. M...

Multivariate Stochastic Volatility: a Review

The literature on multivariate stochastic volatility (MSV) models has developed significantly over the last few years. This paper reviews the substantial literature on specification, estimation, and evaluation of MSV models. A wide range of MSV models is presented according to various categories, namely, (i) asymmetric models, (ii) factor models, (iii) time-varying correlation models, and (iv) ...

Multivariate stochastic volatility

We provide a detailed summary of the large and vibrant emerging literature that deals with the multivariate modeling of conditional volatility of financial time series within the framework of stochastic volatility. The developments and achievements in this area represent one of the great success stories of financial econometrics. Three broad classes of multivariate stochastic volatility models ...

A Multivariate Ornstein-Uhlenbeck Type Stochastic Volatility Model

Using positive semidefinite processes of Ornstein-Uhlenbeck type a multivariate Ornstein-Uhlenbeck (OU) type stochastic volatility model is introduced. We derive many important statistical and probabilistic properties, e.g. the complete second order structure and a state-space representation. Noteworthy, many of our results are shown to be valid for the more general class of multivariate stocha...
