elhmc: An R Package for Hamiltonian Monte Carlo Sampling in Bayesian Empirical Likelihood

no code implementations2 Sep 2022 Dang Trung Kien, Neo Han Wei, Sanjay Chaudhuri

In this article, we describe a {\tt R} package for sampling from an empirical likelihood-based posterior using a Hamiltonian Monte Carlo method.

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

no code implementations2 Sep 2022 Sanjay Chaudhuri, Teng Yin

Furthermore, we discuss Bayesian model selection using empirical likelihood and extend our two-step Metropolis Hastings algorithm to a reversible jump Markov chain Monte Carlo procedure to sample from the resulting posterior.

On a Variational Approximation based Empirical Likelihood ABC Method

no code implementations12 Nov 2020 Sanjay Chaudhuri, Subhroshekhar Ghosh, David J. Nott, Kim Cuc Pham

The expected log-likelihood is then estimated by an empirical likelihood where the only inputs required are a choice of summary statistic, it's observed value, and the ability to simulate the chosen summary statistics for any parameter value under the model.

Maximum Likelihood under constraints: Degeneracies and Random Critical Points

no code implementations3 Oct 2019 Subhro Ghosh, Sanjay Chaudhuri

In the Bayesian setting, we rigorously establish the posterior consistency of procedures based on these ideas, where instead of a parametric likelihood, an empirical likelihood is used to define the posterior distribution.

An easy-to-use empirical likelihood ABC method

no code implementations3 Oct 2018 Sanjay Chaudhuri, Subhro Ghosh, David J. Nott, Kim Cuc Pham

Many scientifically well-motivated statistical models in natural, engineering and environmental sciences are specified through a generative process, but in some cases it may not be possible to write down a likelihood for these models analytically.

Qualitative inequalities for squared partial correlations of a Gaussian random vector

no code implementations12 Mar 2015 Sanjay Chaudhuri

Rules for comparing degree of association among the vertices of such Gaussian graphical models are also developed.
