Methods for comparing center‐specific survival outcomes using direct standardization
(Wiley, 2014-05-30)
The evaluation of center‐specific outcomes is often through survival analysis methods. Such evaluations must account for differences in the distribution of patient characteristics across centers. In the context of censored ...
Multiple imputation of missing covariates for the Cox proportional hazards cure model
(John Wiley and Sons, Inc, 2016-11-20)
Analysis on binary responses with ordered covariates and missing data
(John Wiley & Sons, Ltd., 2007-08-15)
We consider the situation of two ordered categorical variables and a binary outcome variable, where one or both of the categorical variables may have missing values. The goal is to estimate the probability of response of ...
Contrasting treatment‐specific survival using double‐robust estimators
(John Wiley & Sons, Ltd, 2012-12-30)
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 ...
The Role of Childhood Trauma and PTSD in Postpartum Sleep Disturbance

Memory functioning in post‐traumatic stress disorder: objective findings versus subjective complaints
(John Wiley & Sons, Ltd, 2011-08)
Although memory complaints are common in post‐traumatic stress disorder (PTSD), the only published study of objective and subjective memory in PTSD by Roca and Freeman indicates that subjective complaints may not accurately ...
