综合评价中异常值的识别及无量纲化处理方法
Outliers Recognition and the Dimensionless Method in Comprehensive Evaluation
摘要
Abstract
In face of the outliers in comprehensive evaluation,this paper analyses three questions:are there outli-ers in original data if there are outliers,how to recognize them And how to design dimensionless method for all data included in outliers For the judgment and recognition of outliers,we tahe"median"as a reference.Based on this,the outliers can be identified by comparing the distance of the former endpoint to the median and that of the later endpoint to the median.To the dimensionless question,based on the frequently-used linear scale trans-formation(max-min)method, we provide a piecewise dimensionless method by allocating dimensionless value interval to outliers and non-outliers respectively.At last,the validity of this research is illustrated by the compar-ison with the results of available literature.And it is found the methods in this paper can not only recognize outliers moderately,but also promote the proportionality of dimensionless results.关键词
