Table 3. Accuracy, positive (PPV) and negative predictive value (NPV), true positive (TPR) and negative (TNR) rates for serotype and host type predictions.
| Phenotype | Accuracy | PPV | NPV | TPR | TNR |
|---|---|---|---|---|---|
| Serotype | 94.8% | - | - | - | - |
| IAB | 98.5% | 90.0% | 99.2% | 90.0% | 99.2% |
| IC | 97.0% | 71.4% | 100.0% | 100.0% | 96.8% |
| ID | 95.6% | 97.9% | 94.3% | 90.2% | 98.8% |
| IE | 98.5% | 98.4% | 98.6% | 98.4% | 98.6% |
| Host type | 87.4% | - | - | - | - |
| large | 87.4% | 90.7% | 85.9% | 75.0% | 95.2% |
| small | 87.4% | 85.9% | 90.7% | 95.2% | 75.0% |
(PPV) = TP/(TP + FP), (NPV) = TN/(TN+FN), TPR = TP/(TP+FN), and TNR = TN/(TN+FP).
