随机抽取管理学院10名学生，对其4门课程的考试成绩进行统计，如下表所示，这4门课程分别为多元统计分析，运筹学，经济学，管理学.使用主成分分析方法对学生成绩进行分析.学生编号多元统计分析运筹学经济学管理学1778267812637880813757371814557263685315560736678182677708178808668173719706872631057735560>>x1=[77637555316770667057];>>x2=[82787372558181816873];>>x3=[67807163608278737255];>>x4=[81818168736780716360];>>data=[x1;x2;x3;x4]';%输入观测值数据矩阵>>[n,m]=size(data);>>fori=1:m%将数据矩阵中心标准化sddata(:,i)=(data(:,i)-mean(data(:,i)))./std(data(:,i),1);end>>[P,score,egenvalue,t2]=princomp(sddata)%做主成分分析P=-0.55110.3268-0.36240.6769-0.55880.3358-0.2089-0.7289-0.5110-0.11930.84600.0944-0.3505-0.8753-0.3307-0.0398score=-1.3489-0.2567-1.2840-0.0315-1.2458-0.97400.5341-0.2698-0.8704-0.7467-0.58630.73361.16420.3096-0.2225-0.27073.3634-1.56900.3950-0.0572-1.10540.84801.1534-0.2345-1.5954-0.52120.0958-0.1867-0.69920.48720.1005-0.41050.47380.97990.57681.030637
