摘要
自20世纪80年代以来,主成分综合评价方法得到了广泛应用。一些学者认为:主成分综合评价方法能消除指标之间的重复信息,主成分的累积方差贡献率代表综合评价的把握程度,主成分综合评价方法具有降维作用。本文对上述三个问题进行了探讨,提出了不同的观点。
Comprehensive evaluation by principal component analysis has been widely applied since the 1980s. Some scholars think that the comprehensive evaluation method helps eliminate the overlapping information among various indicators, that the cumulated variance contribution ratio of the principal component reflects the credible degree of the comprehensive evaluation, and that the comprehensive evaluation method is effective to dimension reduction. This paper addresses these three issues by putting forward different viewpoints.
