Research on Eztended Cluster of Grey Incidences and Its Application

摘要：

This paper studies extended clusters of grey incidences for indexes in panel data. Firstly it discusses the expression of a panel data by matrix sequence, and describes its geometric characteristic though a cluster of curved surfaces. Thereafter, in three dimensional space, the paper analyzes the geometric similarity of indexes in panel data. According to the principle of grey incidence analysis, it proposes an absolute degree of grey incidences for matrixes, which maintains the consistent form with the classic one. Furthermore the formula of zeroing starting point operator and parameters are redefined. On this basis, the paper constructs the extended incidence matrix of indexes and discusses the cluster analysis process of panel data. Finally, an instance is studied. The results prove the method is effective.
