第六讲常用非参数统计方法(Nonparametric Statistics)前几讲介绍的统计检验方法(如 t 检验、F 检验等)都假定了总体是符合一定的分布(如正态分布等)。总体的分布往往取决于一定的统计指标。例如,正态分布的确定就是由总体平均数μ和总体方差σ~2决定的。统计上
Lecture 6 Nonparametric Statistics The statistical test methods introduced in the previous sections (such as t-test and F-test) assume that the population is consistent with certain distributions (such as normal distribution). The overall distribution often depends on certain statistical indicators. For example, the normal distribution is determined by the population mean μ and the overall variance σ ~ 2. Statistics
