Optimal Treatment Policy Estimation for Recurrent Events with a Competing Terminal Event: An Instrumented Difference-in-Differences Approach
Ritoban Kundu, James Flory, Sean Hennessy +1
Learning reproducible and generalizable optimal treatment policies for chronic diseases requires large, representative populations with long-term follow-up. Administrative health d…
Identification, Estimation, and Inference for Sequential Causally Ordered Mediation Pathways
Ritoban Kundu, Canyi Chen, Peter X. K. Song
Mediation analysis plays an essential role in uncovering the mechanisms by which an exposure influences an outcome through intermediate pathways. While methodological advances for…
Network Structural Equation Models for Causal Mediation and Spillover Effects
Ritoban Kundu, Peter X. K. Song
Social network interference induces complex dependencies where a unit's outcome is influenced not only by its own exposure and mediator but also by those of connected neighbors. In…
A Doubly Robust Framework for Addressing Outcome-Dependent Selection Bias in Multi-Cohort EHR Studies
Ritoban Kundu, Xu Shi, Michael Kleinsasser +3
Selection bias can hinder accurate estimation of association parameters in binary disease risk models using non-probability samples like electronic health records (EHRs). The issue…
Copula Structural Equation Models for Mediation Pathway Analysis
Canyi Chen, Ritoban Kundu, Wei Hao +1
Structural equation models (SEMs) are fundamental to causal mediation pathway discovery. However, traditional SEM approaches often rely on \emph{ad hoc} model specifications when h…
