摘要:

本文讨论的问题估计的概率,一个事件是另一个在给定的情况下的原因。使用结构语义的必要或充分的因果关系(或两者)的概率的定义,我们展示了如何最佳绑定这些数量从实验和观察研究中获得的数据,使最小的假设有关的数据生成过程。特别是,我们通过削弱数据生成假设和推导因果关系概率的理论上的严格界限来加强Pearl(1999)的结果。这些结果精确地描述了如何使用经验数据来解决归因问题和解决与归因相关的决策问题。

英文摘要:

This paper deals with the problem of estimating the probability that one event was a cause of another in a given scenario. Using structural-semantical definitions of the probabilities of necessary or sufficient causation (or both), we show how to optimally bound these quantities from data obtained in experimental and observational studies, making minimal assumptions concerning the data-generating process. In particular, we strengthen the results of Pearl (1999) by weakening the data-generation assumptions and deriving theoretically sharp bounds on the probabilities of causation. These results delineate precisely how empirical data can be used both in settling questions of attribution and in solving attribution-related problems of decision making.
