本文提出了一种拟合比例风险回归模型的方法，当数据包含左、右或区间删失观测值时。给出了检验零回归系数假设的结果，推广了用于比较几条生存曲线的对数等级检验。该方法用于分析动物致瘤性研究和临床试验的数据。
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.
