5.独立样本T检验Stata操作 6.单一样本T检验的R语言操作 1.配对样本T检验(Paired samples t test)的概念: 检验两组相关的样本是否来自具有相同均值的总体。 例:(1)某班学生开学前的数学成绩和期末的数学成绩是否有显著差异; (2)某个运动员训练前的成绩和训练后的成绩是否有显著差异。 配对样本T检验的示意图 2...
至此,我们已通过jamovi、SPSS、Stata、R和SAS演示了“配对样本t检验(Paired Samplest-test)”的实现过程。后期,我们将持续推出其他统计学方法的理论及软件操作系列文章,敬请关注!
Dear Statalisters, I'm trying to do a paired t-test on a matched sample after performing propensity score matching to assess differences in measured characteristics between treated and untreated individuals. I've used psmatch2 to perform the matching. I'm familiar with the syntax to do a pai...

配对样本t检验简称配(成)对t检验(paired/matched t-test),也称关联样本t检验(related-sample t-test),适用于配对设计或自身对照设计的计量资料的比较。配对设计是将受试对象按照某些重要特征(如性别、年龄等可疑混杂因素)配成对子,再将每对中的两...
