Joint Models of Longitudinal Data and Recurrent Events with Informative Terminal Event
Statistics in Biosciences - Tập 4 - Trang 262-281 - 2012
Sehee Kim, Donglin Zeng, Lloyd Chambless, Yi Li
This article presents semiparametric joint models to analyze longitudinal data with recurrent events (e.g. multiple tumors, repeated hospital admissions) and a terminal event such as death. A broad class of transformation models for the cumulative intensity of the recurrent events and the cumulative hazard of the terminal event is considered, which includes the proportional hazards model and the p...... hiện toàn bộ
Information Sets and Excess Zeros in Random Effects Modeling of Longitudinal Data
Statistics in Biosciences - Tập 2 - Trang 81-94 - 2010
Tze L. Lai, Kevin H. Sun, Samuel P. Wong
Marginal regression via generalized estimating equations is widely used in biostatistics to model longitudinal data from subjects whose outcomes and covariates are observed at several time points. In this paper we consider two issues that have been raised in the literature concerning the marginal regression approach. The first is that even though the past history may be predictive of outcome, the ...... hiện toàn bộ
The Causal Effect of Educational Attainment on Completed Fertility for a Cohort of Danish Women—Does Feedback Play a Role?

A Power Prior Approach for Leveraging External Longitudinal and Competing Risks Survival Data Within the Joint Modeling Framework
Statistics in Biosciences - Tập 14 - Trang 318-336 - 2021
Md. Tuhin Sheikh, Ming-Hui Chen, Jonathan A. Gelfond, Joseph G. Ibrahim
In this paper, we propose a new partial borrowing-by-parts power prior for carrying out the analysis of co-longitudinal and survival data within the joint modeling framework. The borrowing-by-parts power prior facilitates borrowing the information from a subset of the data, from a subset of the model parameters, or from the different parts of the joint model. The deviance information criterion is ...... hiện toàn bộ

Semiparametric Bayes Local Additive Models for Longitudinal Data
Statistics in Biosciences - Tập 7 - Trang 90-107 - 2013
Zhaowei Hua, Hongtu Zhu, David B. Dunson
In longitudinal data analysis, a great interest is in assessing the impact of predictors on the time-varying trajectory in a response variable. In such settings, an important issue is to account for heterogeneity in the shape of the trajectory among subjects, while allowing the impact of the predictors to vary across subjects. We propose a flexible semiparametric Bayesian approach for addressing t...... hiện toàn bộ

Bayesian Joint Analysis of Gene Expression Data and Gene Functional Annotations
Statistics in Biosciences - Tập 4 - Trang 300-318 - 2012
Xinlei Wang, Min Chen, Arkady B. Khodursky, Guanghua Xiao
Identifying which genes and which gene sets are differentially expressed (DE) under two experimental conditions are both key questions in microarray analysis. Although closely related and seemingly similar, they cannot replace each other, due to their own importance and merits in scientific discoveries. Existing approaches have been developed to address only one of the two questions. Further, most...... hiện toàn bộ
