摘要

倾向评分匹配是一种统计技术，其中一个治疗病例与一个或多个对照病例匹配基于每个病例的倾向评分。这种匹配可以通过减少选择偏差来帮助加强准实验和观察性研究中的因果论证。在这篇文章中，我们集中讨论如何用一个来自教育领域的例子来进行倾向得分匹配。我们的目标是提供信息，将倾向得分匹配范围内的研究和评估从业人员。

A Step-by-Step Guide to Propensity Score Matching in R

Propensity score matching is a statistical technique in which a treatment case is matched with one or more control cases based on each case’s propensity score. This matching can help strengthen causal arguments in quasi-experimental and observational studies by reducing selection bias. In this article we concentrate on how to conduct propensity score matching using an example from the field of education. Our goal is to provide information that will bring propensity score matching within the reach of research and evaluation practitioners.
