Latent variable models for gene–environment interactions in longitudinal studies with multiple correlated exposures
(Chapman & Hall/CRCWiley Periodicals, Inc., 2015-03-30)
Non-parametric estimation of gap time survival functions for ordered multivariate failure time data
(John Wiley & Sons, Ltd., 2004-06-30)
Times between sequentially ordered events (gap times) are often of interest in biomedical studies. For example, in a cancer study, the gap times from incidence-to-remission and remission-to-recurrence may be examined. Such ...
High School Students' Critical Evaluation of Scientific Resources on the World Wide Web
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-06)
This research explores a new web-based curriculum idea, that of having students write and publish critical web “reviews” of scientific resources as a means of both practicing critical evaluation of web resources, and of ...
A shared random effects model for censored medical costs and mortality
(John Wiley & Sons, Ltd., 2006)
In this paper, we propose a model for medical costs recorded at regular time intervals, e.g. every month, as repeated measures in the presence of a terminating event, such as death. Prior models have related monthly medical ...
Semiparametric inferences for association with semi-competing risks data
(John Wiley & Sons, Ltd., 2005)
In many biomedical studies, it is of interest to assess dependence between bivariate failure time data. We focus here on a special type of such data, referred to as semi-competing risks data. In this article, we develop ...
Export Production in the Subarctic North Pacific over the Last 800 kyrs: No Evidence for Iron Fertilization?
(Kluwer Academic Publishers; The Oceanographic Society of Japan ; Springer Science+Business Media, 2004-01)
The subarctic North Pacific is a high nitrate-low chlorophyll (HNLC) region, where phytoplankton growth rates, especially those of diatoms, are enhanced when micronutrient Fe is added. Accordingly, it has been suggested ...
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)
Sustained striatal ciliary neurotrophic factor expression negatively affects behavior and gene expression in normal and R6/1 mice
(Wiley Subscription Services, Inc., A Wiley Company, 2008-06)
Huntington's disease (HD) is a neurodegenerative disorder caused by an elongation of CAG repeats in the HD gene, which encodes a mutant copy of huntingtin with an expanded polyglutatmine repeat. Individuals who are ...
