Table 4

Classification of free-range and caged eggs using rescaled elemental data of eggshells by PLS-DA and LS-SVM.

Models	Parameters	ERMCCV (%)	Accuracy (%)	Sensitivity (%)	Specificity (%)
PLS-DA	4^a	8.36	91.9	91.1 (41/45)^b	92.7 (38/41)^c
LS-SVM	(700, 5)^d	2.47	95.3	95.6 (43/45)	95.1 (39/41)

^aNumber of PLS-DA latent variables. ^bTP/TP + FN. ^cTN/TN + FP. ^dValues of (σ², γ).
