本文提出利用部分因果信息来更精确地界定制因概率,扩展了因果概率在现实场景中的应用范围。

摘要:

因果概率是个体层面解释和决策的基础,但它们本质上是反事实的,一般情况下无法从数据中直接确定。现有的界限要么忽略可用的协变量,要求完整的因果图,要么依赖于限制性的二元设置,限制了它们的实际应用。在现实应用中,因果信息通常是部分但非微不足道的。本文提出了一种利用部分因果信息界定制因概率的一般框架。我们展示了如何将可用的结构或统计信息系统地纳入优化编程形式化中的约束,从而得到更紧密且正式有效的界限,而无需完全可识别性。这种方法扩展了因果概率在因果知识不完整但有信息的现实场景中的适用性。

英文摘要:

Probabilities of causation are fundamental to individual-level explanation and decision making, yet they are inherently counterfactual and not point-identifiable from data in general. Existing bounds either disregard available covariates, require complete causal graphs, or rely on restrictive binary settings, limiting their practical use. In real-world applications, causal information is often partial but nontrivial. This paper proposes a general framework for bounding probabilities of causation using partial causal information. We show how the available structural or statistical information can be systematically incorporated as constraints in a optimization programming formulation, yielding tighter and formally valid bounds without full identifiability. This approach extends the applicability of probabilities of causation to realistic settings where causal knowledge is incomplete but informative.
