前面我写了多重填补的统计学考虑与SAS实现这篇文章,里面提了一嘴MI的tipping point analysis。小伙伴们在后台私信留言说写一下tipping point analysis。今天它来了。 MNAR缺失模式 我们提到,对于MI的sensitivity analysis,常见的分析就是做tipping point analysis,它主要就是评估在MNAR(missing not at random)缺失模式...

当终点数据存在非随机确实的时候,临床连续型数据常规的分析方法很多就不适用,比如混合线性模型和方差分析模型等,此时就需要使用tipping point analysis来分辨是否常规方法统计结果对缺失数据敏感,如果不敏感的话,说明即使存在非随机缺失数据,对常规分析方法结果影响较小,常规分析方法结果是比较稳健的。 连续终点的临界值分析...

而tipping point analysis就是要做下压力测试,即估计需要数据缺失多大程度上背离MAR,主分析的结果会被推翻(由变为)。特别是在临床试验中,由于我们很难基于收集到的数据有百分百的把握确认MAR的缺失,这个时候,tipping point analysis的结果对于主分析的结论就有一定程度上的验证能力了。
