摘要翻译:
因果分析的许多应用要求回顾性地评估阻止一项事实上已经实施的行动的影响。这个反事实的量,有时被称为“治疗对被治疗者的影响”(ETT)已经被用来评估教育项目,批评公共政策,并证明个人决策的合理性。在这篇论文中,我们探讨了在什么条件下可以从实验和/或观察研究中估计ETT(即,在实验和/或观察研究中确定)。我们证明,当动作调用一个单例变量时,ETT识别的条件有简单的因果图刻画。我们进一步给出了一个图解描述,在此条件下,多重治疗对被治疗者的影响可以被识别,以及ETT估计和可以由介入和观测分布构造的方法。

英文摘要:
  Many applications of causal analysis call for assessing, retrospectively, the effect of withholding an action that has in fact been implemented. This counterfactual quantity, sometimes called "effect of treatment on the treated," (ETT) have been used to to evaluate educational programs, critic public policies, and justify individual decision making. In this paper we explore the conditions under which ETT can be estimated from (i.e., identified in) experimental and/or observational studies. We show that, when the action invokes a singleton variable, the conditions for ETT identification have simple characterizations in terms of causal diagrams. We further give a graphical characterization of the conditions under which the effects of multiple treatments on the treated can be identified, as well as ways in which the ETT estimand can be constructed from both interventional and observational distributions.
