WebSep 26, 2024 · We show that Cohen’s Kappa and Matthews Correlation Coefficient (MCC), both extended and contrasted measures of performance in multi-class classification, are correlated in most situations, albeit can differ in others. WebCohen's kappa symbolized by the lower case Greek letter, κ (7) is a robust statistic useful for either interrater or intrarater reliability testing. Similar to correlation coefficients, it can range from −1 to +1, where 0 represents the amount of agreement that can be expected from random chance, and 1 represents perfect agreement between ...
