评估供应商绩效需要有基于数据的洞察力,而领先的统计软件 Minitab 是一款功能强大且易于使用的解决方案。本博客将介绍如何使用 Minitab 中的 2-Proportion Test(双样本比例检验)分析两个供应商(供应商 A 和供应商 B)的延迟交付率。通过深入研究数据并执行双样本比例检验,我们可以了解哪个供应商的延迟交付率更高...

Only used for testing the null that a single proportion equals a given value, or that two proportions are equal; ignored otherwise. 运行结果:p>0.05,表明区域2的未完成率与区域1的没有差异性。 0.2199+0.7801=1,说明给出的是alternative下的显著性检验;感觉双侧检验更适合一些 1.2 空间分析的一般流程 ...

Two-sample tests for equality of proportion with continuity correction were performed to compare the rates of preterm birth, LBW, macrosomia, SGA, LGA, and inappropriate birthweights, and Welch’s two-sample t-test was performed for birthweight as a continuous outcome. Generalized linear models fo...
