About us
Welcome to our site! Currently, our group's research focuses on adaptive randomization designs and their statistical inference.
More specifically, we are interested in the impact of network interference in A/B testing; unobserved covariates in covariate-adaptive designs; issues in personalized medicine; statistical applications to clinical trials, etc.

- Package 'groupRAR' uploaded.
The 'groupRAR' package is designed for group response-adaptive randomization procedures, and it includes the standard non-group response-adaptive randomization method as a special case within a comprehensive framework. It can also handle group response-adaptive randomization procedures with delayed and missing responses.
