Fitting stratified proportional odds models by amalgamating conditional likelihoods
(John Wiley & Sons, Ltd., 2008-10-30)
Classical methods for fitting a varying intercept logistic regression model to stratified data are based on the conditional likelihood principle to eliminate the stratum-specific nuisance parameters. When the outcome ...
Nonparametric comparison of two survival functions with dependent censoring via nonparametric multiple imputation
(John Wiley & Sons, Ltd., 2009-02-01)
When the event time of interest depends on the censoring time, conventional two-sample test methods, such as the log-rank and Wilcoxon tests, can produce an invalid test result. We extend our previous work on estimation ...

Interval estimation of the mean response in a log-regression model
(John Wiley & Sons, Ltd., 2006-06-30)
A standard approach to the analysis of skewed response data with concomitant information is to use a log-transformation to normalize the distribution of the response variable and then conduct a log- regression analysis. ...
Morality and the limits of societal values in health care allocation
(John Wiley & Sons, Ltd., 2002-04)
In this paper, we consider whether there is a clear moral justification for the proposal that societal value preferences (SVPs) should be included in Cost Effectiveness Analyses (CEA) of health care resource allocations. ...
A discrete-state discrete-time model using indirect observation
(John Wiley & Sons, Ltd., 2006-03-30)
This research was motivated by a desire to model the progression of a chronic disease through various disease stages when data are not available to directly estimate all the transition parameters in the model. This is a ...
A Bayesian hierarchical approach to multirater correlated ROC analysis
(John Wiley & Sons, Ltd., 2005)
In a common ROC study design, several readers are asked to rate diagnostics of the same cases processed under different modalities. We describe a Bayesian hierarchical model that facilitates the analysis of this study ...
Indirect estimation of a discrete-state discrete-time model using secondary data analysis of regression data
(John Wiley & Sons, Ltd., 2009-07-20)
Multi-state models of chronic disease are becoming increasingly important in medical research to describe the progression of complicated diseases. However, studies seldom observe health outcomes over long time periods. ...
Simulating the Allocation of Organs for Transplantation
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-11)
The demand for donated organs greatly exceeds supply and many candidates die awaiting transplantation. Policies for allocating deceased donor organs may address equity of access and medical efficacy, but typically must be ...
