聚类分析法
一、需求分析
聚类分析，亦称群分析或点群分析，它是研究多要素事物分类问题的数量方法。其基本原理是，根据样本自身的属性，用数学方法按照某些相似性或差异性指标，定量地确定样本之间的亲疏关系，并按这种亲疏关系程度对样本进行聚类。
在聚类分析中，聚类要素的选择是十分重要的，它直接影响分类结果的准确性和可靠性。
不同要素的数据往往具有不同的单位和量纲，因而其数值的差异可能是很大的，这就会对分类结果产生影响。因此当分类要素的对象确定之后，在进行聚类分析之前，还要对聚类要索进行数据处理。
假设有m个被聚类的对象，每一个被聚类对象都有x1，x2，…，xn个要素构成。它们所对应的要素数据可用表2-10给出。在聚类分析中，常用的聚类要素的数据处理方法有如下几种。
1)总和标准化。分别求出各聚类要素所对应的数据的总和，以各要素的数据除以该要素数据的总和，即
2)标准差的标准化，即
3)极大值标准化，即
4)极差的标准化，即
距离的计算
如果我们把每一个分类对象的n个聚类要素看成n维空间的n个坐标轴，则每一个分类对象的n个要素所构成的n维数据向量就是n维空间中的一个点。这样，各分类对象之间的差异性就可以由它们所对应的n维空间中点之间的距离度量。常用的距离有
1)绝对值距离
2)欧氏距离
3)明科夫斯基距离
4)切比雪夫距离。当明科夫斯基距离p→∞时，有
选择不同的距离，聚类结果会有所差异。
