倾向性评分方法可以用多种方式进行,不同的方式产生不同的目标人群,两种常用的倾向性评分方法是倾向评分匹配(propensity score matching,PSM)和倾向分数加权(propensity score weighting,PSW)。 倾向评分匹配: 倾向评分匹配是使用最广泛的一种倾向性评分方法。而在倾向性评分匹配中,又以1:1近邻匹配被使用最广泛。 在观...
The propensity score method involves calculating the conditional probability (propensity) of being in the treated group (of the exposure) given a set of covariates, weighting (or sampling) the data based on these propensity scores, and then analyzing the outcome using the weighted data. I first ...

This article considers weighting strategies for balancing covariates. We define a general class of weights—the balancing weights—that balance the weighted distributions of the covariates between treatment groups. These weights incorporate the propensity score to weight each group to an analyst-selected ...
