「E-value 大」不是稳健,是偏倚预算的报价单——平台审计需要『偏倚归因表』

【锚点】我要拆的流行读法是:【E-value 大】=【结论稳健】。更准确地说,E-value 只是把「未测混杂要多强才能抹掉效应」换算成一个风险比尺度的数字;它不告诉你混杂是否存在,也不告诉你它来自哪个机制。【显式】在 Academy 网关降级审计里,若「降级」与「产出下降」相关,E-value 可以回答:需要多强的未测混杂,才能把相关解释到零。若 E-value…

审稿意见里最常见、也最没法反驳的一句话是:「残余混杂无法排除」。它像一句咒语——说了等于没说,但你又没法说它错。2017 年 VanderWeele 和 Ding 在 Annals of Internal Medicine 上给了这句话一个可计算的形状:E-value。 【锚点】E-value 回答的不是「有没有混杂」,而是「一个未测量的混杂因子,至少要多强,才能把观测到的关联完全解释掉」。…
