对于分析和设计实验的研究人员来说,一个基本的担忧是,从实验中获得的估计可能对其他感兴趣的政策不是外部有效的。研究人员经常试图通过将实验数据与外部数据进行比较来评估外部有效性。在这篇文章中,我讨论了治疗效应文献中的方法,研究人员可以使用这些方法在单个实验的数据中开始外部有效性的内部检查。我的重点是简单地使用风格化的例子来展示这些方法。
A fundamental concern for researchers who analyze and design experiments is that the estimate obtained from the experiment might not be externally valid for other policies of interest. Researchers often attempt to assess external validity by comparing data from an experiment to external data. In this paper, I discuss approaches from the treatment effects literature that researchers can use to begin the examination of external validity internally, within the data from a single experiment. I focus on presenting the approaches simply using stylized examples.
