Definition
The kappa coefficient, sometimes known as Cohen’s kappa after its originator, is a nonparametric statistic that assesses the degree of association between categorical variables. It was originally developed as a way to assess agreement among raters when subjective qualitative judgments were made. It can be thought of as a correlation coefficient describing the relation or shared variance between two categorical-level variables.
