Study on interval functional data weighting methods
Aiming at the problems of information loss or excessive computational complexity of functional comprehensive evaluation caused by excessive data,this paper proposes a comprehensive evaluation method based on interval functional data,and proposes a new"global"pull-out grade method to determine the weight coefficient for the particularity of the comprehensive evaluation problem supported by the interval functional data table.Finally,taking Yiwu Commodity Prosperity Index as an example,the"global"pull-out grade method in the form of functional data and interval functional data is used to empower it,and then the evaluation research is carried out.
