Comparing the small sample performance of several variance estimators under competing risks
(John Wiley & Sons, Ltd., 2007-02-28)
We examine several variance estimators for cumulative incidence estimators that have been proposed over time, some of which are derived from asymptotic martingale or counting process theory, and some of which are developed ...
A Bayesian analysis of small n sequential multiple assignment randomized trials (snSMARTs)
(Wiley Periodicals, Inc.SIAM, 2018-11-20)
Meta‐analysis of gene‐environment interaction exploiting gene‐environment independence across multiple case‐control studies
(Wiley Periodicals, Inc.Springer Verlag, 2017-10-30)
Estimation for paired binomial data with application to radiation therapy
(John Wiley & Sons, Ltd., 2001-11-30)
We compare and contrast several different methods for estimating the effect of treatment when responses are paired binomial observations. The ratio of binomial probabilities is the parameter of interest, while the binomial ...
Social security health insurance for the informal sector in Nicaragua: a randomized evaluation
(John Wiley & Sons, Ltd., 2010-09)
This article presents the results from an experimental evaluation of a voluntary health insurance program for informal sector workers in Nicaragua. Costs of the premiums as well as enrollment location were randomly allocated. ...
Training of the next generation of biostatisticians: a call to action in the U.S.
(John Wiley & Sons, Ltd., 2006-10-30)
Two workshops (2001, 2003) were held by the National Institutes of Health (NIH) to examine the need to train more biostatisticians in the U.S. to meet the increasing opportunities in the biomedical research enterprise. The ...
On Bayesian methods of exploring qualitative interactions for targeted treatment

Developing multicomponent interventions using fractional factorial designs
(John Wiley & Sons, Ltd., 2009-09-20)
Multicomponent interventions composed of behavioral, delivery, or implementation factors in addition to medications are becoming increasingly common in health sciences. A natural experimental approach to developing and ...
Generalizing the TITE-CRM to adapt for early- and late-onset toxicities
(John Wiley & Sons, Ltd., 2005)
Due to the staggered entry of subjects in phase I trials, some subjects will only be partially through the study when others are ready to be enrolled. Nonetheless, many phase I designs focus solely upon whether or not ...
Semiparametric Bayesian modeling of random genetic effects in family-based association studies
(John Wiley & Sons, Ltd., 2009-01-15)
We consider the inference problem of estimating covariate and genetic effects in a family-based case-control study where families are ascertained on the basis of the number of cases within the family. However, our interest ...
