| 本文目的是介绍与无序样品聚类分析有关的基本概念、计算方法、两个实例以及使用SAS实现计算的方法。基本概念包括名义变量、有序变量、定性变量、区间变量、比率变量、距离；计算方法涉及第一组距离计算公式（共15个）和度量两类样品之间距离大小的离差平方和法（Ward法）计算公式；两个实例分别是“我国27个少数民族16岁男孩身体形态学数据”和“1995年我国14个省、直辖市的劳动卫生监督数据”；对两个实例的数据进行了无序样品聚类分析，并对SAS输出结果做出了解释。 |
| 英文摘要: |
| The purpose of this article was to introduce the basic concepts， calculation methods， two examples and the implementation of SAS calculation methods related to the cluster analysis of disordered samples. The basic concepts included nominal variables， ordered variables， qualitative variables， interval variables ratio variables and distance. The calculation methods involved the first set of 15 distance calculation formulas and the Ward's method calculation formula for measuring the distance between two clusters of samples. The data in the two examples were "physical morphology data of 16-year-old boys from 27 ethnic minorities in China" and "labor health supervision data from 14 provinces and municipalities in China in 1995". Using SAS software， Cluster analysis of disordered samples was performed on the data from two instances， and the SAS output results were explained. |
