I read How to calculate specificity from accuracy and sensitivity, but I have two diagnostic performance measures more. Please correct me if I am wrong: if
- Positive predictive value=TP/(TP+FP)
- Negative predictive value=TN/(TN+FN)
- Cohen's kappa=1-[(1-Po)/(1-Pe)]
Can I calculate the accuracy if I know the sensitivity, specificity, positive and negative predictive values? Can I calculate the Cohen's kappa too?
Unfortunately, that situation could happen if you read an abstract of a scientific work.
