time-dependent covariates

基本解释

It is so called "time-dependent covariates" that the values of covariates change over time.
共變數的值會隨著時間而改變時，我們稱之爲時間相依之共變數。
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，可加危險（AH）模型被廣泛地應用於生存分析數據，模型的協變量可以假設爲時間獨立或時間相關。
