摘要
应用主成分分析原理,以少数的综合变量取代原有的多维变量,使数据结构简化,把原指标综合成几个主成分,再以这几个主成分的贡献率为权数进行加权平均,构造出一个综合评价函数.文章应用该原理对23家电器企业的实力进行了综合评价,其结果是合理可信的.
If we apply the theory of principle component analysis, which can use less comprehensive variables to instead of the multivariate variables, this method can simplify the structure of the data and aggregate the original index into several principal components. Regarding the contribution rate of this principal component as right, count weighted average and make up a comprehensive function. This text applies the theory of principal component analysis to assess the evaluation of 23 companies in real life, and the result is convincing.
