Abstract

This paper is a continuation of our previous works on correlation coefficients of Atanassov’s intuitionistic fuzzy sets (A-IFSs). The Pearson’s coefficient we discuss here yields the strength of relationship between the A-IFSs and also indicates the direction of correlation (positive or negative). The proposed correlation coefficient takes into account all three terms describing an A-IFS (membership values, non-membership values, and the hesitation margins).
