n-Dimensional Fuzzy Vectors and Type-2 Fuzzy Contingency Table Analysis

Abstract

The authors defined type-2 fuzzy contingency table concerned two variable, and proposed fuzzy portfolio analysis method that applied it. Also, we have reported questionnaire analysis on classes as application of it. In this paper, we propose a definition of dimensional reduction of n-dimensional fuzzy vectors. Furthermore, we show its effectiveness through ordering improvement items in fuzzy portfolio analysis.
