Model Accuracy by Number of Neighborsa
| accuracy (%) | |||
|---|---|---|---|
| number of neighbors | number of chemicals (n) | Toxtree | COEH (not conservative) |
| 0 | 139 | 68 | 77 |
| 1–3 | 80 | 73 | 78 |
| >3 | 32 | 78 | 59 |
The COEH model had a higher accuracy for chemicals with no neighbors in the data set, while Toxtree had a higher accuracy when there were more neighbors (i.e., greater than 3). This suggests that COEH has a broader coverage than Toxtree.
