| 中文简介: |  尽管直接和间接因果关系的用语相对普遍，但我认为，如果不作进一步说明，它在科学上通常无济于事。这项评估是基于其在社会和生物医学重要实例中所产生的困惑的反复经验。在回顾了我根据潜在结果和分配机制的概念对因果推理的观点之后，本演讲将讨论两种不同的方式来规范使用该术语的情况下出现的问题。 第一个基于第二种是基于复合分配机制的概念，这只是一般分配机制的特例。将使用简单的人工示例来说明这两种概念化之间的差异，并表明当使用直接和间接术语描述因果关系时，很容易混淆。 即使是非常好的R.A。费希尔是这种混乱的受害者，将对此进行记录。 |
| 课程简介: | Although the terminology of direct and indirect causal effects is relatively common, I believe that it is generally scientifically unhelpful without further explication. This assessment is based on repeated experience with the confusion it creates in important examples in the social and biomedical sciences. After reviewing my perspective on causal inference based on the concepts of potential outcomes and assignment mechanisms, this presentation will discuss two distinct ways to formalize the issues that arise in circumstances where this terminology is used. The first is based on the concept of principal stratification, and the second is based on the concept of a compound assignment mechanism, which is just a special case of general assignment mechanisms. Simple artificial examples will be used to illustrate the differences between the two conceptualizations, and to show that it is easy to become confused when using the direct and indirect jargon to describe causal effects. Even the great R.A. Fisher was a victim of this confusion, as will be documented. |
