Robust Sequential Hypothesis Testing with Generalized Estimating Equations for Incomplete Clustered and Longitudinal Data
Nathan T. Provost, Abdus S. Wahed
Existing sequential generalized estimating equation methodology for longitudinal and group-correlated data focuses on narrow hypotheses concerning treatment efficacy and often make…
Interim Analysis in Sequential Multiple Assignment Randomized Trials for Survival Outcomes
Zi Wang, Yu Cheng, Abdus S. Wahed
Sequential multiple assignment randomized trials mimic the actual treatment processes experienced by physicians and patients in clinical settings and inform the comparative effecti…
A Risk-Ratio-Based Marginal Sensitivity Model for Causal Effects in Observational Studies
Md Abdul Basit, Mahbub A. H. M. Latif, Abdus S Wahed
In observational studies, the identification of causal estimands depends on the no unmeasured confounding (NUC) assumption. As this assumption is not testable from observed data, s…
Sensitivity Analysis of Inverse Probability Weighting Estimators of Causal Effects in Observational Studies with Multivalued Treatments
Md Abdul Basit, Mahbub A. H. M. Latif, Abdus S Wahed
One of the fundamental challenges in drawing causal inferences from observational studies is that the assumption of no unmeasured confounding is not testable from observed data. Th…
Interim Monitoring in Sequential Multiple Assignment Randomized Trials
Liwen Wu, Junyao Wang, Abdus S. Wahed
A sequential multiple assignment randomized trial (SMART) facilitates comparison of multiple adaptive treatment strategies (ATSs) simultaneously. Previous studies have established…
Bayesian Nonparametric Estimation for Dynamic Treatment Regimes with Sequential Transition Times
Yanxun Xu, Peter Mueller, Abdus S. Wahed +1
Dynamic treatment regimes in oncology and other disease areas often can be characterized by an alternating sequence of treatments or other actions and transition times between dise…
