¹ Sensitivity, the ratio of true A to the sum of true A and false A. ² Specificity B, the ratio of true B to the sum of true B and false B. ³ Specificity C, the ratio of true C to the sum of true C and false C. ⁴ Overall predictive accuracy, the ratio of the sum of true A, true B, and true C to the sum of true A, true B, true C, false A, false B, and false C. ⁵ MCC, Matthews correlation coefficient. ⁶ OOB estimation.
