I've made an excel file to calculate common additional data usually required together with KAPPA.
- Observed proportions
- Expected proportion of agreement
- Proportion of positive agreement
- Proportion of negative agreement
- Prevalence index
- Bias index
I hope that someone might find it useful in the future!
