摘要

Harrell(1982)将一致性指数(c-index)应用于生存数据。就其基本形式而言，该指数依赖于审查，但这个问题可以有效地解决。更重要的是，Harrell的c指数不能用于时变效应和/或时变协变量，并提出了几种推广。我们研究其中的一些，探索它们之间的差异，指出这些概括之间的基本区别，并强烈支持一种概括。

note on generalisations of the concordance index for survival data

Concordance index (c-index) was adapted to survival data by Harrell (1982). In its basic form, the index depends on censoring, however the issue can be effectively dealt with. More importantly, Harrell's c-index cannot be used with time-varying effects and/or time-dependent covariates, and several generalisations were proposed. We look at some of them, explore their differences, point to a basic difference between these generalisations, and strongly favour one type of generalisation.
