Table 2.

Specificity, recall, precision, F1-score, accuracy and kappa for the classification of SVMs for the external validation (n = 30) of fresh samples using Vis and MSI data and of frozen-thawed samples using MSI data considering three classes: 0% pork-100% chicken (0%); adulterated (A); 100% pork-0% chicken (100%).
