| 摘 要： | 针对应用主成分法或因子分析进行综合评价时存在的缺点，提出了分组主成分评价法．即先用因子分析法对变量进行分组，然后再分别对各组变量进行主成分评价，既保持了主成分法的优点，又克服了它评价中的缺点，使综合评价结果更趋合理，并用该方法对实例进行了分析．

| Abstract: | Aiming at the shortcoming of the comprehensive evaluation by principal component analysis, this paper presents a method called grouped principal component evaluation. Namely, the variables are divided into groups by factor analysis, then with principal component the variable of each group are evaluated separately. Thus it can keep the virtue of principal component analysis and overcomes its defects. So that it can improve the rationality of comprehensive evaluation result. Finally,an example is analysed with this method and better result is obtained. |
