چکیده

This paper introduces a new model for panel data with Markov-switching GARCH effects. The incorporates series-specific hidden Markov chain process that drives the parameters. To cope high-dimensionality of parameter space, exploits cross-sectional clustering series by first assuming soft pooling through hierarchical prior distribution two-step procedure, and then introducing effects in space nonparametric distribution. proposed inference are evaluated simulation experiment. results suggest is able to recover true value parameters number groups each regime. An empirical application 78 assets SP\&100 index from $6^{th}$ January 2000 $3^{rd}$ October 2020 also carried out using two-regime switching model. findings shows presence 2 3 clusters among constituents second regime, respectively.

A Bayesian MCMC Algorithm for Markov Switching GARCH models

Markov switching GARCH models have been developed in order to address the statistical regularity observed in financial time series such as strong persistence of conditional variance. However, Maximum Likelihood Estimation faces a implementation problem since the conditional variance depends on all the past history of state. This paper shows that this problem can be handled easily in Bayesian in...

Consistency of Bayesian nonparametric Hidden Markov Models

We are interested in Bayesian nonparametric Hidden Markov Models. More precisely, we are going to prove the consistency of these models under appropriate conditions on the prior distribution and when the number of states of the Markov Chain is finite and known. Our approach is based on exponential forgetting and usual Bayesian consistency techniques.

Bayesian nonparametric hidden semi-Markov models

There is much interest in the Hierarchical Dirichlet Process Hidden Markov Model (HDPHMM) as a natural Bayesian nonparametric extension of the ubiquitous Hidden Markov Model for learning from sequential and time-series data. However, in many settings the HDP-HMM’s strict Markovian constraints are undesirable, particularly if we wish to learn or encode non-geometric state durations. We can exten...

Markov Switching GARCH models for Bayesian Hedging on Energy Futures Markets

A new Bayesian multi-chain Markov Switching GARCHmodel for dynamic hedging in energy futures markets is developed: a system of simultaneous equations for return dynamics on the hedged portfolio and futures is introduced. More specifically, both the mean and variance of the hedged portfolio are assumed to be governed by two unobserved discrete state processes, while the futures dynamics is drive...

Bayesian Markov Regime-Switching Models for Cointegration

This paper introduces a Bayesian Markov regime-switching model that allows the cointegration relationship between two time series to be switched on and off over time. Unlike classical approaches for testing and modeling cointegration, the Bayesian Markov switching method allows for estimation of the regime-specific model parameters via Markov Chain Monte Carlo and generates more reliable estima...
