Parametric tests are designed for idealized data. In contrast, nonparametric tests are designed for real data: skewed, lumpy, having a few warts, outliers, and gaps scattered about. Nonparametric methods are workhorses of modern science, which should be part of every scientist's competence.
Web非参数检验(Nonparametric tests)是统计分析方法的重要组成部分，它与参数检验共同构成统计推断的基本内容。参数检验是在总体分布形式已知的情况下，对总体分布的参数如均值、方差等进行推断的方法。 但是，在数据分析过程中，由于种种原因，人们往往无法对总体分布形态作简单假定，此时参数 ...
