摘要
本文对居中型和区间型两种适度指标进行论证和例证,考察了这两种数据处理方法对主成分和因子分析这种综合评价结果的影响。另外,本文用文献①"初始化"思想对极差法进行分析,得到结论,即处理后数据的协方差矩阵不仅消除了指标量纲和数量级的影响,还能包含原始数据的全部信息。
Argument and illustration of some kinds of appropriate indicators is done in this paper, such as the indicators of medium and interval. And the paper looks at the effect of the comprehensive evaluation results from the two data processing method on principal components analysis and factor analysis. In addition, this article analyses the process according to the method of 'Initialization' in the literature [1], then come to a conclusion of which the data covariance matrix after processing not only eliminate the influence of index dimension and order of magnitude, and also can contain all the information in the raw data.
