论文摘要
基本倾向评分方法学旨在在比较一种主动治疗与一种对照处理的情况下平衡多元预处理协变量。实际设置通常涉及比较两种以上的处理，在这种治疗中，比基本治疗控制更复杂的对比是相关的。在这里，我们提出了使用特异性倾向得分（CSP）的使用。 CSP允许创建相对于指定对比的分叉和它们所跨越的多元空间平衡的单位治疗组。
Basic propensity score methodology is designed to balance multivariate pre-treatment covariates when comparing one active treatment with one control treatment. Practical settings often involve comparing more than two treatments, where more complicated contrasts than the basic treatment-control one,(1,-1), are relevant. Here, we propose the use of contrast-specific propensity scores (CSPS). CSPS allow the creation of treatment groups of units that are balanced with respect to bifurcations of the specified contrasts and the multivariate space spanned by them.
