Block-Wise Pseudo-Marginal Metropolis-Hastings
Published 2016-03-30The pseudo-marginal Metropolis-Hastings approach is increasingly used for Bayesian inference in statistical models where the likelihood is analytically intractable but can be estimated unbiasedly, such as random effects ...Open AccessWorking Paper -
Fast Inference for Intractable Likelihood Problems using Variational Bayes
Published 2016-03-30Variational Bayes (VB) is a popular statistical method for Bayesian inference. The existing VB algorithms are restricted to cases where the likelihood is tractable, which precludes their use in many interesting models. ...Open AccessWorking Paper -
A New Measure of Vector Dependence, with an Application to Financial Contagion
Published 2016-03-11We propose a new nonparametric measure of association between an arbitrary number of random vectors. The measure is based on the empirical copula process for the multivariate marginals, corresponding to the vectors, and ...Open AccessWorking Paper -
Exact ABC using Importance Sampling
Published 2015-09-23Approximate Bayesian Computation (ABC) is a powerful method for carrying out Bayesian inference when the likelihood is computationally intractable. However, a draw- back of ABC is that it is an approximate method that ...Open AccessWorking Paper -
GEL Estimation for Heavy-Tailed GARCH Models with Robust Empirical Likelihood Inference
Published 2015-09-11We construct a Generalized Empirical Likelihood estimator for a GARCH(1,1) model with a possibly heavy tailed error. The estimator imbeds tail-trimmed estimating equations allowing for over-identifying conditions, asymptotic ...Open AccessWorking Paper
