A Bayesian Framework for Causal Analysis of Recurrent Events in Presence of Immortal Risk

no code implementations6 Apr 2023 Arman Oganisian, Anthony Girard, Jon A. Steingrimsson, Patience Moyo

Estimation with observational claims data is challenging because while membership in the target population is defined in terms of eligibility criteria, treatment is rarely assigned exactly at the time of eligibility.

Bayesian Semiparametric Model for Sequential Treatment Decisions with Informative Timing

no code implementations29 Nov 2022 Arman Oganisian, Kelly D. Getz, Todd A. Alonzo, Richard Aplenc, Jason A. Roy

A g-computation procedure is used to compute a posterior over potential survival probability that is adjusted for time-varying confounding.

A Practical Introduction to Bayesian Estimation of Causal Effects: Parametric and Nonparametric Approaches

2 code implementations15 Apr 2020 Arman Oganisian, Jason A. Roy

We provide an introduction to Bayesian inference for causal effects for practicing statisticians who have some familiarity with Bayesian models and would like an overview of what it can add to causal estimation in practical settings.

Bayesian Nonparametric Cost-Effectiveness Analyses: Causal Estimation and Adaptive Subgroup Discovery

no code implementations11 Feb 2020 Arman Oganisian, Nandita Mitra, Jason Roy

Effectiveness (often measured as increased survival time) and accumulated cost tends to be right-censored in many applications.
