Modeling the random effects covariance matrix for longitudinal data with covariates measurement error Autor Hoque, Md Erfanul, Torabi, Mahmoud

“… Generalized linear mixed models (GLMMs) are commonly used to analyze such data. It is typically assumed that the random effects covariance matrix is constant among subjects in these models…”

Joint modeling of recurrent events and a terminal event adjusted for zero inflation and a matched design Autor Xu, Cong, Chinchilli, Vernon M., Wang, Ming

“… In some scenarios, a certain large portion of subjects may not have any recurrent events during the study period due to nonsusceptibility to events or censoring; thus, the zero…”

Dynamic reliability assessment and prediction for repairable systems with interval-censored data Autor Peng, Yizhen, Wang, Yu, Zi, YanYang, Tsui, Kwok-Leung, Zhang, Chuhua

“… Due to instrument malfunctions, staff omissions and imperfect inspection strategies, field reliability data are often subject to interval censoring, making dynamic reliability assessment become a difficult task…”

Augmented likelihood for incorporating auxiliary information into left-truncated data Autor Shi, Yidan, Zeng, Leilei, Thompson, Mary E., Tyas, Suzanne L.

“… A one-step Monte-Carlo Expectation-Maximization algorithm is developed to calculate an augmented likelihood through creating pseudo-data sets which extend the form and conditions of the observed sample. The method is illustrated by both a real dataset and simulation studies…”

Semiparametric Latent ANOVA Model for Event-Related Potentials Autor Cheng-Han, Yu, Li, Meng, Vannucci, Marina

“… A major goal is to link ERP characteristic components to subject-level covariates. Existing methods typically follow two-step approaches, first identifying ERP components using peak detection methods and then relating them to the…”
