Table 4.
Classification accuracies for BIC and BICres.
| BIC | BICres | |||
|---|---|---|---|---|
| All | < 109 M⊙ | All | < 109 M⊙ | |
| TP | 135 | 124 | 118 | 107 |
| TN | 281 | 276 | 316 | 311 |
| FP | 45 | 39 | 10 | 4 |
| FN | 5 | 0 | 22 | 17 |
| Accuracy | 89% | 93% | 93% | 97% |
Notes. We show the number of early-type galaxies that were classed as true positives (TP), true negatives (TN), false positives (FP), and false negatives (FN), based on the BIC classifications relatively to our nucleation classification from multi-component decompositions (see text for more detail). We calculate the accuracy as (TP + TN)/(TP + TN + FP + FN).
