...Yanli Zhai; Gege Luo; Dang Luo Purpose The purpose of this paper is to construct a grey incidence model for panel data that can reflect the incidence direction and degree between indicators. Design/methodology/approach Firstly, this paper introduces the concept of a negative matrix...

... is introduced to represent the complete information of relevant data. The industrial ecological evaluation involves a comprehensive complex system, which belongs to the panel data analysis problem. The improved grey panel clustering evaluation model is applied to grade the industrial ecological development...

...Dang Luo; Nana Zhai Purpose The purpose of this paper is to establish a two-stage grey cloud clustering model under the panel data for the multi-attribute clustering problem with three-parameter interval grey number to evaluation of agricultural drought resistance grade of 18 cities in Henan...

... relational method of spatial-temporal panel data from the perspective of the development trend of the object dimension indicators and the performance difference between the time dimension indicators. Design/methodology/approach From the different perspectives of object dimension and time dimension...

...Honghua Wu; Zhongfeng Qu Purpose The paper aims to propose a clustering model for panel data. More specifically, the paper aims to construct a gray incidence model for panel data to solve the classification with multi-factors and multi-attributes. Design/methodology/approach The paper opted...

... model based on cone volume and other methods so as to evaluate the logistics development of node cities. The dimensionality of three-dimensional panel data is reduced by factor analysis at first. Then, the gray target decision-making method based on cone volume is adopted to evaluate the development...
