Index

Definition and formula

Acc

(TP + TN)/(TP + TN + FP + FN)

AUC

area under the receiving operating characteristic curve

F-score

2 · TP/(2TP + FP + FN)

Sen

TP/(TP + FN)

Sp

TN/(TN + FP)

MCC

TP â‹… TN - FN â‹… FP TP + FN â‹… TP + FP â‹… TN + FN â‹… TP + FP

  1. TP (true positive); TN (true negative); FP (false positive); FN (false negative);
  2. Acc, overall accuracy; AUC, area under ROC; Sen, sensitivity; Sp, specificity; F-score, 2×precision×sensitivity/(precision+sensitivity); MCC, Matthews’s correlation coefficient.
