condition positive (P)
the number of real positive cases in the data
condition negative (N)
the number of real negative cases in the data
true positive (TP)
eqv. with hit
true negative (TN)
eqv. with correct rejection
false positive (FP)
eqv. with false alarm, Type I error
false negative (FN)
eqv. with miss, Type II error
sensitivity, recall, hit rate, or true positive rate (TPR)
specificity or true negative rate (TNR)
precision or positive predictive value (PPV)
negative predictive value (NPV)
miss rate or false negative rate (FNR)
fall-out or false positive rate (FPR)
false discovery rate (FDR)
false omission rate (FOR)
accuracy (ACC)
is the harmonic mean of precision and sensitivity
Matthews correlation coefficient (MCC)
Informedness or Bookmaker Informedness (BM)
Markedness (MK)
