本文建议将同时检验的结果报告为调整后的 P 值，这样，如果单个假设的调整后的 P 值小于所选的 α 显着性水平，则该假设将被拒绝，实验误差率不超过 α。给出了方差分析中多重比较的调整 P 值的示例，以及基于 Bonferroni 程序和 Holm (1 979, 斯堪的纳维亚统计杂志 6, 65-70)、Hochberg (1988, Biometrika 75, 800-802) 和 Hommel (1988, Biometrika 75, 383-386）。修改后的基于 Bonferroni 的程序比原始 Bonferroni 程序强大得多，值得更广泛的使用。除上述内容外，还概述了为任何封闭测试程序获取调整后的 P 值的程序。
This paper proposes that results from simultaneous tests be reported as adjusted P-values such that, if the adjusted P-value for an individual hypothesis is less than the chosen significance level of alpha, then the hypothesis is rejected with an experimentwise error rate of no more than alpha. Examples are given of adjusted P-values for multiple comparisons in the analysis of variance and of adjusted P-values based on the Bonferroni procedure and modifications of that procedure by Holm (1 979, Scandinavian Journal of Statistics 6, 65-70), Hochberg (1988, Biometrika 75, 800-802), and Hommel (1988, Biometrika 75, 383-386). The modified Bonferroni-based procedures are much more powerful than the original Bonferroni procedure, and they deserve wider use. In addition to the above, a procedure is outlined for obtaining adjusted P-values for any closed test procedure.
