实验五聚类分析1.下表是1999年我国省、自治区的城市规模结构特征的一些数据,请通过聚类分析将这些省、自治区进行分类。

(2)对原始数据进行标准化处理,变量间相近性度量采用相关系数,类间相近性度量计算类平均距离d=1-r; % 进行数据变换,把相关系数转换为距离d=tril(d);% 取出矩阵d的下三角元素d=nonzeros(d); % 取出非零元素d=d'; % 化成行向量z=linkage(d,'average') % 计算类平均距离dendrogram(z) % 作聚类图T=cluster(z,'maxclust',3) % 把变量划分成3类for i=1:3tm=find(T==i); % 求第i类的对象tm=reshape(tm,1,length(tm)); % 变成行向量fprintf('第%d类的有指标%s\n',i,int2str(tm)) % 显示分类结果end运行结果:z =第1类的有指标:4;第2类的有指标:2 3;第3类的有指标:1 5;从聚类图中可以看出,如果将5各指标分为3类,城市首位度、四城市指数两个指标之间具有较大相关性,最先被聚到一起,其次首位城市规模和城市规模中位值也具有一定相关性,被聚为第二类,基尼指数单独为一类。
这样就可以从五个指标中选定三个指标进行分析:1x :城市规模,2x :城市首位度,4x :基尼指数。
(3)根据这三个指标对27个地区进行聚类分析。
首先对每个变量的数据分别进行标准化处理,样本间相似性采用欧氏距离度量,类间距离的计算选用类平均距离。
