An Anatomy of Event Studies: Hypothetical Experiments, Exact Decomposition, and Weighting Diagnostics
Zhu Shen, Ambarish Chattopadhyay, Yuzhou Lin +1
In recent decades, event studies have emerged as a central methodology in health and social research for evaluating the causal effects of staggered interventions. In this paper, we…
Scalable kernel balancing weights in a nationwide observational study of hospital profit status and heart attack outcomes
Kwangho Kim, Bijan A. Niknam, José R. Zubizarreta
Weighting is a general and often-used method for statistical adjustment. Weighting has two objectives: first, to balance covariate distributions, and second, to ensure that the wei…
Multiply Robust Federated Estimation of Targeted Average Treatment Effects
Larry Han, Zhu Shen, Jose Zubizarreta
Federated or multi-site studies have distinct advantages over single-site studies, including increased generalizability, the ability to study underrepresented populations, and the…
Doubly Robust Counterfactual Classification
Kwangho Kim, Edward H. Kennedy, José R. Zubizarreta
We study counterfactual classification as a new tool for decision-making under hypothetical (contrary to fact) scenarios. We propose a doubly-robust nonparametric estimator for a g…
Isolation in the construction of natural experiments
José R. Zubizarreta, Dylan S. Small, Paul R. Rosenbaum
A natural experiment is a type of observational study in which treatment assignment, though not randomized by the investigator, is plausibly close to random. A process that assigns…
