反之,在给定propensity score下,treatment和untreatment组之间的协变量分布仍然存在显著差异的话,说明score学的不好。 可参考文献:: An Introduction to Propensity Score Methods for Reducing the Effects of Confounding in Observational Studies.

plot(SumSt,type="balance")#可绘制估算的倾向值的直方图("hist")、估算的倾向值的密度图("density")、均衡统计量(("balance") 其中除了IPW,ATT加权(treated)、重叠加权(overlap)、匹配加权(matching)、熵加权(entropy)都可以使协变量在组间达到均衡。 最后,我们用重叠加权后组间均衡和结果分析作为此次推文的结...
We propose the use of propensity score matching methods and implement them using data from the NSW experiment. Following Lalonde (1986), we pair the experimental treated units with non-experimental comparison units from the CPS and PSID and compare the estimates of ...

Propensity score methods,propensity score matchingin particular, have been of particular interest in the health policy literature. It is speculated that the reason for this interest is related to the fact that with propensity score methods it is possible to mimic the feel of the familiar and salie...
Moreover, we estimate the average treatment effect with multivariate analysis and compared the results with the estimates of propensity score matching techniques. The Medstat MarketScan Data Base provided data for use in empirical examples of the utility of several matching methods. We conducted ...
(ii) selecting a subset of comparison units similar to the treatment units is difficult because units must be compared across a high-dimensional set of pretreatment characteristics. We discuss the use of propensity score matching methods, and implement them using data from the NSW experiment. ...
