| 摘 要： | 分组主成份分析是将主成份分析和因子分析相结合的一种改进模型,实际应用中有一定的意义。将其和因子分析进行比较,并在此基础之上,引进变异系数作进一步的改进,建立综合评价模型,提高了评价结果的合理性和客观性,用我国各地区中等职业教育的发展情况做模型检验,取得了较好的效果。

| Abstract: | Sub-group principal component analysis is an improved model of principal component analysis and factor analysis.Its practical application is significant,and compared with factor analysis,the introduction of the coefficient of variation for further improvement,in the coefficient of variation,a comprehensive evaluation model is established.The evaluation results can improve the rationality and objectivity,with development of secondary vocational education to do empirical analysis of the situation and has achi... |
