医学研究中参数统计的一些方法常有一个关于总体分布的前提,如U检验法要求总体分布为正态分布等。但在实际工作中有些资料不合这种要求,则需要应用一种不必依赖某一专门的总体分布的统计方法,称为“不顾分布情况的统计方法”或“非参数统计方法”,该方法易掌握,故又有“简易统计方法”之称。 R分析法(Ridit Analgsis)为非参数统计方法之一,又名参照单位分析法。
Some methods of parameter statistics in medical research often have a premise that the overall distribution, such as the U test requires the general distribution of the normal distribution. However, in practice, some data do not meet this requirement, and it is necessary to apply a statistical method that does not depend on a specific overall distribution, which is called “disregarding statistical methods of distribution” or “non-parametric statistical methods”. This method is easy to use. Master, it is also known as the “simple statistical method.” Ridit Analgsis is one of the non-parametric statistical methods, also known as the reference unit analysis.
