多类实验中个体处理效应分布与分位数的改进推断

研究问题
个体处理效应不能由观测直接识别时,如何减轻分布与分位数随机化推断的最坏情形保守性,提高实验中的检验功效?
方法与思路
作者分别合并处理组与对照组的效应推断,以及显式控制处理组中大效应个体的数量,并扩展到抽样实验和匹配准实验。
材料陈述的贡献
摘要称,两种改进方法在模拟和应用中取得明显功效增益,其思想也在抽样实验与匹配准实验的扩展中发挥互补作用。
阅读关注点
应核对分布和分位数的推断目标、两组结果的合并规则、大效应人数的控制方法,以及匹配准实验中有效性所需条件。
阅读边界
所给版本为 arXiv 预印本,同行评审与期刊接收未核实;摘要未列出改进方法的有效性条件,也未报告功效提升的数值范围。

原文摘要

Understanding treatment effect heterogeneity has become increasingly important in many fields. In this paper we study distributions and quantiles of individual treatment effects to provide a more comprehensive and robust understanding of treatment effects beyond usual averages, despite they are more challenging to infer due to nonidentifiability from observed data. Recent randomization-based approaches offer finite-sample valid inference for treatment effect distributions and quantiles in both completely randomized and stratified randomized experiments, but can be overly conservative by assuming the worst-case scenario where units with large effects are all assigned to the treated (or control) group. We introduce two improved methods to enhance the power of these existing approaches. The first method reinterprets existing approaches as inferring treatment effects among only treated or control units, and then combines the inference for treated and control units to infer treatment effects for all units. The second method explicitly controls for the actual number of treated units with large effects. Both simulation and applications demonstrate the substantial gain from the improved methods. These methods are further extended to sampling-based experiments as well as quasi-experiments from matching, in which the ideas for both improved methods play critical and complementary roles.
