- Correlation coefficient, hesitant fuzzy sets, scoring function, extension principle.
The previous correlation measures for hesitant fuzzy sets proposed in the literature only capture the strength of the correlations. We present a new approach based on the classical Pearson correlation coefficient for crisp values. In this way we can express not only the strength of the relationship between two hesitant fuzzy sets, but also whether they are positively or negatively associated.
