Consider a probit regression problem in which Y 1 , ..., Y n are independent Bernoulli random variables such that Pr.Y i D 1/ D Φ.x T i β/ where x i is a p-dimensional vector of known covariates that are associated with Y i , β is a p-dimensional vector of unknown regression coefficients and Φ./ denotes the standard normal distribution function. We study… (More)

We consider Bayesian analysis of data from multivariate linear regression models whose errors have a distribution that is a scale mixture of normals. Such models are used to analyze data on financial returns, which are notoriously heavy-tailed. Let π denote the intractable posterior density that results when this regression model is combined with the… (More)

The reversible Markov chains that drive the data augmentation (DA) and sandwich algorithms define self-adjoint operators whose spectra encode the convergence properties of the algorithms. When the target distribution has uncountable support, as is nearly always the case in practice, it is generally quite difficult to get a handle on these spectra. We show… (More)

Let f be an integrable function on an infinite measure space (S, S, π). We show that if a regenerative sequence {Xn} n≥0 with canonical measure π could be generated then a consistent estimator of λ ≡ S f dπ can be produced. We further show that under appropriate second moment conditions, a confidence interval for λ can also be derived. This is illustrated… (More)

It is known that the robit regression model for binary data is a robust alternative to the more popular probit and logistic models. The robit model is obtained by replacing the normal distribution in the probit regression model with the Student's t distribution. Unlike the probit and logistic models, the robit link has an extra degrees of freedom (df)… (More)

A sequence of random variables {X n } n≥0 is called regenerative if it can be broken up into iid components. The problem addressed in this paper is to determine under what conditions is a Markov chain regenerative. It is shown that an irreducible Markov chain with a countable state space is regenerative for any initial distribution if and only if it is… (More)

Introduction The pink shrimp, familiar to most Floridians as either food or bait shrimp, is ubiquitous in both seagrass-and mangrove-dominated south Florida coastal waters. The pink shrimp, Farfantepenaeus duorarum, is a biological indicator in the Southern Estuaries Module of MAP, the Monitoring and Assessment Program of CERP. The South Florida Fish and… (More)
