Table 2.
Prediction results of external samples by the human–animal PLSDA model using six latent variables.

|---|---|---|---|
| Human | 50 | 0 | 5/5 |
| Cat | 0 | 30 | 3/3 |
| Dog | 0 | 30 | 3/3 |
| Rabbit | 0 | 30 | 3/3 |
| Horse | 0 | 30 | 3/3 |
| Cow | 0 | 30 | 3/3 |
| Pig | 0 | 30 | 3/3 |
| Opossum | 0 | 30 | 3/3 |
| Raccoon | 1 | 29 | 3/3 |
| Deer | 0 | 30 | 3/3 |
| Elk | 0 | 30 | 3/3 |

The table shows results at the spectral level and the donor level (when more than 50% of spectra from one donor are correctly classified).
