Figure 3

E-nose-MOS-LDA-SA model: supervised discrimination (original grouped data) of cv. Arbequina olive oils extracted without (control, •) or with the addition of olive leaves (1%, w/w) from cv. Arbequina (▲) or cv. Santulhana (■) based on four signals recorded by two sensors (S1_INT, S1_MAX, S2_SUM, and S2_MEAN).
