Regarding Kappa Value in Cross Validation
Kappa values can be positive or negative depending on the type (level of agreement +ve, level of disagreement -ve). But in cross-validation how the final value of kappa is calculated? Are the negative values converted to positive and then the average kappa of all the folds are taken into consideration or are they are averaged directly?
