常见的非参数检验方法包括Mann-Whitney U检验、Wilcoxon秩和检验、Kruskal-Wallis H检验等。 三、数据是否为配对数据的考量 数据的配对性也是选择假设检验方法时需要考虑的因素之一。配对数据指的是两组数据之间存在一一对应关系的数据,如同一样本在不同时间或不同条件下的测量值。对于配对数据,可以采用配对样本t检验或...

coin包提供了一个置换检验的一般性框架,可以分析一组变量相对于其他任意变量,是否与第二组变量(可根据一个区组变量分层)相互独立。而且independence_test()函数可以让我们从置换角度来思考大部分传统检验,进而在面对无法用传统方法解决的问题时,使用户可以自己构建新的统计检验。当然,这种灵活性也是有门槛的:要正确使用...
