@evaristoc all my variables are categorical and while doing cross validation my kappa is coming as 0 , I checked variance among variables it was not 0 should I go ahead ignoring kappa. Any thoughts..

@hchawla437

There should be something wrong with your analysis. I would suggest to check the confusion matrix or the specific values (false positives/negatives, true positives/negatives) manually and see what it is going on wrong.

You are training only on the labelled data I guess.
