time-dependent covariates

基本解釋

It is so called "time-dependent covariates" that the values of covariates change over time.
共變數(shù)的值會(huì)隨著時(shí)間而改變時(shí)，我們稱之為時(shí)間相依之共變數(shù)。
Recently, additive hazards(AH)models are extensively applied to analyze survival data, in which covariates are assumed to be time-independent or time-dependent.
最近以來(lái)，可加危險(xiǎn)（AH）模型被廣泛地應(yīng)用于生存分析數(shù)據(jù)，模型的協(xié)變量可以假設(shè)為時(shí)間獨(dú)立或時(shí)間相關(guān)。
