Abstract

Covariate-adaptive designs are a class of experimental design methods that dynamically adjust treatment allocation probabilities to achieve balanced covariates across treatment groups. Because of their strengths in enhancing treatment group comparability, increasing the precision of treatment effect estimation, and producing more convincing experimental results, these designs are extensively employed in randomized controlled settings, including clinical trials, economic field experiments, and online A/B testing. This talk first provides a methodological review of various covariate-adaptive design approaches and then discusses a recent advancement in the field, which proposes a novel and unified framework for covariate-adaptive designs. The challenges and solutions in analyzing data collected from covariate-adaptive designs will also be addressed.
