倾向性得分(Propensity Score,PS)就是在给定一组协变量的条件下,研究对象被分配到处理组的条件概率,这个概率一般通过logit或者probit模型来获取。倾向性得分本身并不能控制混杂,而是需要通过进一步的匹配、分层、回归校正、加权等方式来达到分析的目的。 既往倾向性得分分析一些笔记: 倾向性得分匹配(PSM); 倾向性得分匹...
敏感性越高，意味着潜在偏倚越可能影响研究推论；反之，则影响较小。对于希望深入了解PS敏感性分析的读者，可以参考《Analysis of Observational Health Care Data Using SAS》、《Propensity Score Analysis: A Primer and Tutorial》以及《Practical Propensity Score Methods Using R》等资源。图 PS之后的敏感性分析接...
Propensity score analysis can be used to balance the differences in the groups, which can be used in a number of ways to reduce biased conclusions regarding effectiveness. A review of propensity scoring studies was conducted for this chapter, where the limited number of evaluations of criminal ...
propensity score matching analysis -回复 什么是倾向评分匹配分析(propensity score matching analysis)? 倾向评分匹配分析(propensity score matching analysis)是一种观察性研究的方法,用于解决观察数据中存在的选择性偏倚问题。该方法通过建立一个倾向评分模型,估计个体在选择干预(treatment)或对照组(controlgroup)的概率,...

propensity score analysis 篇一: Propensity score analysis (PSA) is a statistical technique used in observational studies to estimate causal effects. It is particularly useful in situations where it is not possible or ethical to conduct randomized controlled trials, and the researcherwants to address ...
The propensity score analysis is one of the most widely used methods for studying the causal treatment effect in observational studies. This paper studies treatment effect estimation with the method of matching weights. This method resembles propensity score matching but offers a number of new ...
