This paper develops a method for fitting the proportional hazards regression model when the data contain left-, right-, or interval-censored observations. Results given for testing the hypothesis of a zero regression coefficient lead to a generalization of the log-rank test for comparison of several survival curves. The method is used to analyze data from an animal tumorigenicity study and also a clinical trial.
本文提出了一种在数据包含左删失、右删失或区间删失观测值时拟合比例风险回归模型的方法。用于检验零回归系数假设的结果导致了用于比较多条生存曲线的对数秩检验的推广。该方法用于分析一项动物致瘤性研究以及一项临床试验的数据。
