Empirical Bayes for compound adaptive experiments
Karun Adusumilli, Jiaying Gu, Junfan Tao
We investigate Empirical Bayes (EB) methods in the context of compound adaptive experiments, where the arm distribution in each experiment follows a normal distribution with an unk…
Designing Persuasive Experiments
Karun Adusumilli, Abhi Vemulapati
Incentives in experimental design are often misaligned: experimenters design and finance experiments to seek regulatory approval, while regulators seek to maximize social-welfare.…
You've Got to be Efficient: Ambiguity, Misspecification and Variational Preferences
Karun Adusumilli
This article introduces a framework for evaluating statistical decisions under both prior ambiguity and likelihood misspecification. We begin with an ambiguity set - a frequentist…
Continuous time asymptotic representations for adaptive experiments
Karun Adusumilli
This article develops a continuous-time asymptotic framework for analyzing adaptive experiments -- settings in which data collection and treatment assignment evolve dynamically in…
Optimal tests following sequential experiments
Karun Adusumilli
Recent years have seen tremendous advances in the theory and application of sequential experiments. While these experiments are not always designed with hypothesis testing in mind,…
