Using random effects in the modeling of homogeneous Poisson processes (HPP) has proved effective (Cook and Lawless (2007) and Gongjun et al. (2015)). We (Kh...

BibTeX reference

Inferences about the prevalence of a given disease or condition can be drawn from results of a diagnostic test applied to a sample from the target population...

BibTeX referenceSample size calculations for hierarchical Poisson and zero-inflated Poisson regression models

In biomedical research there is a growing interest in the use of hierarchical Poisson regression models. Although sample size calculations for testing pa...

BibTeX reference

Wavelets have been successfully used for nonparametric function estimation, but a major challenge in density and hazard estimation is that the function must ...

BibTeX reference

Our main interest is the prediction of future events for recurrent event processes. We intend to build a Bayesian model, based on sound philosophical princip...

BibTeX referencePower and Sample Size Calculations for Poisson and Zero-Inflated Poisson Regression Models

Although sample size calculations for testing a parameter in the Poisson regression model have been previously done, very little attention has been given to ...

BibTeX reference

In this study, we compare various computational approaches to Bayesian small area estimation of proportions in logistic regression models. The basic idea con...

BibTeX reference

A challenge in many applications of non-parametric curve estimation is that the function must satisfy some (lower and/or upper) variable order constraints (f...

BibTeX reference

One of the most important aspects of profiling health care providers or services is constructing a model that is flexible enough to allow for random variatio...

BibTeX reference

Here we study hierarchical Bayesian estimation of a monotone hazard rate for both complete and randomly right censored data. We propose two methods of comp...

BibTeX reference

We develop a nonparametric Bayesian functional estimation method, using monotone wavelet approximation, for hazard estimation from randomly right censored d...

BibTeX reference

The Cox proportional hazards model has become the model of choice to use in analyzing the effects of covariates on survival data. However, this assumption ha...

BibTeX referenceQuasi-Likelihood Estimation for Ornstein-Uhlenbeck Diffusion Observed at Random Time Points

In this paper, we study the quasi-likelihood estimator of the drift parameter <img src="/cgi-bin/mimetex.cgi?\theta"> in the Ornstein-Uhlenbeck diffusion pr...

BibTeX reference

The authors study the application of the bootstrap to a class of estimators which converge at a nonstandard rate to a nonstandard asymptotic distribution. T...

BibTeX reference

This paper discusses a Bayesian functional estimation method, based on Fourier series, for the estimation of the hazard rate from randomly right-censored dat...

BibTeX reference

In this paper, we are concerned with the statistical methodology of epidemiological surveillance; that is, the ongoing procedure of analyzing and interpreti...

BibTeX referenceA Unified Bayesian Approach to Small Area Estimation of Mean Parameters in Generalized Linear Models

In this study, we present a unified Bayesian approach to small area estimation of mean parameters in generalized linear models. The basic idea consists of in...

BibTeX reference

There is increased interest in rating types of hospitals or geographical regions containing hospitals on the basis of their performance in the provision of ...

BibTeX referenceExact Analysis of a Paired Sibling Study

A data set on categories of congenital heart malformations for sibling pairs (with different malformations) of Fraser and Hunter (1975) is analyzed exactly ...
