Semiparametric Models for Practice Effects in Longitudinal Cognitive Trajectories: Application to an Aging Cohort Study
Y. Xu, T. Wu, A. Van Dyne +3
Background: True cognitive longitudinal decline can be obscured by repeated testing, which is called practice effects (PEs). We developed a modeling framework that aligns participa…

Why Is the Double-Robust Estimator for Causal Inference Not Doubly Robust for Variance Estimation?
Hao Wu, Lucy Shao, Toni Gui +6
Doubly robust estimators (DRE) are widely used in causal inference because they yield consistent estimators of average causal effect when at least one of the nuisance models, the p…

Semiparametric Regression Models for Explanatory Variables with Missing Data due to Detection Limit
Jasen Zhang, Lucy Shao, Kun Yang +10
Detection limit (DL) has become an increasingly ubiquitous issue in statistical analyses of biomedical studies, such as cytokine, metabolite and protein analysis. In regression ana…
