若干两样本检验功效的蒙特卡洛研究AI 解读

The powers of several two-sample tests are compared by simulation for small samples from exponential and Weibull distributions with and without censoring. The tests considered include the F test, a modification for samples that are from Weibull distributions, Cox's test, Peto & Peto's log rank test, their generalized Wilcoxon test, a modified log rank test, and a generalized Wilcoxon test of Gehan. When samples are from exponential distributions, with or without censoring,…

比较任意右删失样本的广义Wilcoxon检验AI 解读

Summary. A distribution-free two-sample test is proposed that is an extension of the Wilcoxon test to samples with arbitrary censoring on the right. The test is
