Correct Equation for accuracy, specificity, sensitivity?

Rana Abubakar @Rana-Abubakar

22 April 2020 0 2K Report

I am confused to get correct accuracy equation,

Most of the paper used this equation Accuracy = (T N + TP)/(TP + FP + F N + T N)× 100

some of papers found with this equation Accuracy = (T P +TN)/( T P+FP+FN+TN)

Which one is correct?
