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
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...
Rhetorical Analysis Of 'The Tipping Point' In, “The Tipping Point,” Gladwell employs the rhetorical appeal, logos, to prove that individuals can make enormous changes in society. Gladwell identifies “connectors” using logos through statistics, “Anyone who has ever acted, in other words, can...
The tipping point analysis has been a useful sensitivity analysis for multiple imputation to assess the robustness of the deviations from the MCAR or MAR assumptions. It aims to find out how severe departures from MAR will overturn the conclusions from primary analysis. If the departures are consid...

Moving the epidemic tipping point through topologically targeted social distancing 论文地址: 一种社会制度的流行阈值是指当一种疾病在该社会制度中传播时,其感染率和恢复率超过流行阈值时,疾病便会在该社会中进行流行性传播。在没有药物干预措施(即疫苗)的情况下,控制特定疾病的唯一方法是通过社会距离等非药物干预...
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。
