面向处理效应异质性学习的自适应实验

研究问题
如何专门设计随机实验以学习处理效应异质性,并在实验过程中根据累计结果调整数据收集,提高识别高效应亚组的效率?
方法与思路
作者提出响应自适应实验的设计与分析框架,依据实验中累计证据序贯更新数据收集机制,统一自适应富集与响应自适应随机分配。
材料陈述的贡献
摘要称,框架能更有效识别处理效应最大的亚组,并补充电商A/B测试和临床试验设计;作者提供理论说明及合成数据模拟支持。
阅读关注点
应核对适应性分配规则、探索与亚组筛选如何协调、效应估计及推断如何处理分配依赖,以及统计效率提升的比较基准与条件。
阅读边界
这是预印本,同行评审及期刊接收未核实。摘要未给出具体理论条件、误差控制或真实实验结果,效率结论不能外推至所有自适应设计。

原文摘要

Understanding treatment effect heterogeneity has become an increasingly popular task in various fields, as it helps design personalized advertisements in e-commerce or targeted treatment in biomedical studies. However, most of the existing work in this research area focused on either analyzing observational data based on strong causal assumptions or conducting post hoc analyses of randomized controlled trial data, and there has been limited effort dedicated to the design of randomized experiments specifically for uncovering treatment effect heterogeneity. In the manuscript, we develop a framework for designing and analyzing response adaptive experiments toward better learning treatment effect heterogeneity. Concretely, we provide response adaptive experimental design frameworks that sequentially revise the data collection mechanism according to the accrued evidence during the experiment. Such design strategies allow for the identification of subgroups with the largest treatment effects with enhanced statistical efficiency. The proposed frameworks not only unify adaptive enrichment designs and response-adaptive randomization designs but also complement A/B test designs in e-commerce and randomized trial designs in clinical settings. We demonstrate the merit of our design with theoretical justifications and in simulation studies with synthetic e-commerce and clinical trial data.
