ABSTRACT
Inspired by the pioneering work of Rubin [Bayesian inference for causal effects: the role of randomization. Ann Stat. 1978;6:34–58], we employ the potential outcomes framework to develop a finite-population Bayesian causal inference framework for randomized controlled factorial designs with binary outcomes, which are common in medical research. As demonstrated by simulated and empirical examples, the proposed framework corrects the well-known variance over-estimation issue of the classic ‘Neymanian’ inference framework, under various settings.
