New two-step Metropolis-Hastings algorithm enhances Bayesian empirical likelihood methods

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel two-step Metropolis-Hastings algorithm designed to improve the efficiency of Markov chain Monte Carlo (MCMC) sampling for Bayesian empirical likelihood (BayesEL) methods. This new approach addresses the complexities and non-convexity issues that have previously limited the application of BayesEL, particularly in areas like simultaneous quantile regression. The algorithm facilitates sampling from BayesEL posteriors by using current parameter values to propose new values for the remaining parameters, and it can be extended to Bayesian model selection through a reversible jump MCMC procedure.

    A Two-step Metropolis Hastings Method for Bayesian Empirical Likelihood Computation with Application to Quantile Regression and Bayesian Model Selection

    arXiv:2209.01269v2 Announce Type: replace-cross Abstract: Empirical likelihood-based methods have been used under the Bayesian framework (BayesEL) in recent times. For statistical inference, these methods require efficient Markov chain Monte Carlo (MCMC) samplers for drawing obse…
