Statistical measures used to assess the performance of the models.

Measure	Equation
Accuracy (Acc)	$\frac{\mathit{TP}+\mathit{TN}}{\mathit{TP}+\mathit{FN}+\mathit{TN}+\mathit{FP}}$
Specificity (Sp)	$\frac{\mathit{TN}}{\mathit{TN}+\mathit{FP}}$
Sensitivity (Sn)	$\frac{\mathit{TP}}{\mathit{TP}+\mathit{FN}}$
F1 Score (F1)	$\frac{2\times \mathit{TP}}{2\times \mathit{TP}+\mathit{FP}+\mathit{FN}}$
Error rate	1 − Accuracy
