In comparing two survival distributions, a Mantel-Haenszel statistic can be computed after each death as a non-linear two-sample rank statistic. The distributions of both the maximum and terminal statistics in such a sequence are studied numerically, in the absence of censoring, and appropriate critical values are determined. The maximum statistic is applied to simultaneous inference, and both the maximum and terminal statistics are used as the basis for early stopping procedures (especially in the pseudo-sequential context). Procedures based on the two statistics are compared for power and for early decision properties such as stopping index and (for exponential distributions) stopping time.
在比较两个生存分布时，每次死亡后可以计算一个Mantel-Haenszel统计量作为非线性双样本秩统计量。在无删失的情况下，对这样一个序列中的最大统计量和终末统计量的分布进行了数值研究，并确定了合适的临界值。最大统计量用于同时推断，最大统计量和终末统计量都用作早期停止程序的基础（特别是在伪序贯情况下）。比较了基于这两个统计量的程序在功效以及早期决策特性（如停止指标和（对于指数分布）停止时间）方面的表现。
