Common binary classification measures

Measure	Definition
ACC	$= \frac{TP + TN}{TP + TN + FP + FN}$
PPV	$= \frac{TP}{TP + FP}$
TPR	$= \frac{TP}{TP + FN}$
FNR	$= \frac{FP}{FN + TP}$
FPR	$= \frac{FP}{FP + TN}$
TNR	$= \frac{TN}{TN + FP}$
PT	$= \frac{\sqrt{TPR (1 - TNR)} + TNR - 1}{TPR + TNR - 1}$
F1	$= \frac{2 TP}{2 TP + FP + FN}$
MCC	$= \frac{TP \times TN - FP \times FN}{\sqrt{(TP + FP) (TP + FN) (TN + FP) (TN + FN)}}$
