摘要翻译：
本文讨论了从一组观测变量的统计数据和以有向无环图形式编码的定性因果知识的组合中预测行动或干预对系统的影响的问题。DAG表示一组称为结构方程模型(SEM)的线性方程组，其系数是代表直接因果效应的参数。只有当因果效应由数据唯一确定时，才能从模型中得到可靠的定量结论。也就是说，如果模型存在唯一的参数化，使其与数据兼容。如果是这种情况，则该模型称为标识。本文的主要结果是递归SEM模型辨识的一般充分条件。

英文摘要：
  The paper concerns the problem of predicting the effect of actions or interventions on a system from a combination of (i) statistical data on a set of observed variables, and (ii) qualitative causal knowledge encoded in the form of a directed acyclic graph (DAG). The DAG represents a set of linear equations called Structural Equations Model (SEM), whose coefficients are parameters representing direct causal effects. Reliable quantitative conclusions can only be obtained from the model if the causal effects are uniquely determined by the data. That is, if there exists a unique parametrization for the model that makes it compatible with the data. If this is the case, the model is called identified. The main result of the paper is a general sufficient condition for identification of recursive SEM models.
