对比较两种生存时间分布的各种方法的特性进行了理论分析。结果主要旨在指导分析方法的选择，以进行治疗与对照等简单比较，但主要含义相当普遍，说明了不同模型在一系列条件下的性能。对于大多数模型，都有一个参数指定感兴趣的比较，并且可以为该参数计算每次观察的费舍尔信息，并为比较提供简洁的基础。其中两个模型是半参数的，其他模型基于指数分布，有或没有额外的变异源。
A theoretical analysis is made of the properties of various methods for comparing two distributions of survival time. The results are intended primarily to guide the choice of method of analysis for such simple comparisons as of a treatment versus a control, but the main implications are fairly general, illustrating the performance of different models in a range of conditions. For most of the models there is a parameter specifying the comparison of interest and the Fisher information per observation can be calculated for that parameter, and provides a succinct basis for comparison. Two of the models are semiparametric and the others are based on exponential distributions with or without extra sources of variability.
