Savage score statistics are employed to develop a test for comparing survival distributions with right-hand singly censored data. The procedure is motivated by the interest in developing a powerful method for determining differences when true survival distributions cross. Examination of small-sample characteristics under the null hypothesis indicate that asymptotic critical values yield a slightly conservative test. Power of the test compares favorably with other criteria, including the modified Smirnov procedure, particularly if there is a single crossing of the survival curves.
采用萨维奇评分统计量来开发一种用于比较具有右单删失数据的生存分布的检验方法。该程序的动机在于，人们希望开发一种强大的方法，以便在真实生存分布交叉时确定差异。在原假设下对小样本特征的检验表明，渐近临界值会产生一个略为保守的检验。该检验的功效与其他标准相比具有优势，包括修正的斯米尔诺夫程序，特别是在生存曲线只有一次交叉的情况下。
