MCMC‐driven importance samplers

open access: yesApplied Mathematical Modelling, 2022
Monte Carlo sampling methods are the standard procedure for approximating complicated integrals of multidimensional posterior distributions in Bayesian inference. In this work, we focus on the class of Layered Adaptive Importance Sampling (LAIS) scheme, which is a family of adaptive importance samplers where Markov chain Monte Carlo algorithms are ...

MCMC and GLMs for estimating regression parameters: Evidence from non-life Egyptian insurance sector [PDF]

open access: yesJournal of Humanities and Applied Social Sciences, 2019
Purpose – The purpose of this study is to estimate the linear regression parameters using two alternative techniques. First technique is to apply the generalized linear model (GLM) and the second technique is the Markov Chain Monte Carlo (MCMC) method ...

pexm: A JAGS Module for Applications Involving the Piecewise Exponential Distribution

open access: yesJournal of Statistical Software, 2021
In this study, we present a new module built for users interested in a programming language similar to BUGS to fit a Bayesian model based on the piecewise exponential (PE) distribution.

Globally Centered Autocovariances in MCMC [PDF]

open access: yesJournal of Computational and Graphical Statistics, 2022
Autocovariances are a fundamental quantity of interest in Markov chain Monte Carlo (MCMC) simulations with autocorrelation function (ACF) plots being an integral visualization tool for performance assessment. Unfortunately, for slow-mixing Markov chains, the empirical autocovariance can highly underestimate the truth.

TI-Stan: Adaptively Annealed Thermodynamic Integration with HMC †

open access: yesProceedings, 2019
We present a novel implementation of the adaptively annealed thermodynamic integration technique using Hamiltonian Monte Carlo (HMC). Thermodynamic integration with importance sampling and adaptive annealing is an especially useful method for estimating ...

An MCMC approach to classical estimation [PDF]

open access: yesJournal of Econometrics, 2003
This paper studies computationally and theoretically attractive estimators referred here as to the Laplace type estimators (LTE). The LTE include means and quantiles of Quasi-posterior distributions defined as transformations of general (non-likelihood-based) statistical criterion functions, such as those in GMM, nonlinear IV, empirical likelihood ...

Testing MCMC code

open access: yesCoRR, 2014
Markov Chain Monte Carlo (MCMC) algorithms are a workhorse of probabilistic modeling and inference, but are difficult to debug, and are prone to silent failure if implemented naively. We outline several strategies for testing the correctness of MCMC algorithms.

Estimation for coefficient of variation of an extension of the exponential distribution under type-II censoring scheme

open access: yesOpen Physics, 2017
The coefficient of variation [CV] has several applications in applied statistics. So in this paper, we adopt Bayesian and non-Bayesian approaches for the estimation of CV under type-II censored data from extension exponential distribution [EED].

MCMC METHODS FOR DIFFUSION BRIDGES [PDF]

open access: yesStochastics and Dynamics, 2008
We present and study a Langevin MCMC approach for sampling nonlinear diffusion bridges. The method is based on recent theory concerning stochastic partial differential equations (SPDEs) reversible with respect to the target bridge, derived by applying the Langevin idea on the bridge pathspace.
