Joint Group-Based Trajectory Modeling for Paired Repeated Measures: An Application to Audiometric Phenotypes and Dietary Associations
Ying Chen, Sharon Curhan, Kenneth I. Vaden +2
The assumption of conditional independence in conventional group-based trajectory modeling (GBTM) is often violated by paired repeated-measures data with heterogeneous trajectory p…
Generalized Estimating Equations for Hearing Loss Data with Specified Correlation Structures
Zhuoran Wei, Hanbing Zhu, Sharon Curhan +2
Due to the nature of pure-tone audiometry test, hearing loss data often has a complicated correlation structure. Generalized estimating equation (GEE) is commonly used to investiga…
Estimating intracluster correlation for ordinal data
Benjamin W. Langworthy, Zhaoxun Hou, Gary C. Curhan +2
Purpose: In this paper we consider the estimation of intracluster correlation for ordinal data. We focus on pure-tone audiometry hearing threshold data, where thresholds are measur…
Analytical method for detecting outlier evaluators
Yujie Wu, Sharon Curhan, Bernard Rosner +2
Epidemiologic and medical studies often rely on evaluators to obtain measurements of exposures or outcomes for study participants, and valid estimates of associations depends on th…
