mediumAI-checkedEvaluation Metrics

A binary classifier has the confusion counts TP = 40, FN = 10, FP = 10, TN = 40. What is its Matthews correlation coefficient, MCC=TP⋅TN−FP⋅FN(TP+FP)(TP+FN)(TN+FP)(TN+FN)\mathrm{MCC} = \frac{TP\cdot TN - FP\cdot FN}{\sqrt{(TP+FP)(TP+FN)(TN+FP)(TN+FN)}}?

a number between -1 and 1
