Discriminant functions elaborated based on the tocopherols composition.
| Functions | Wilks’ lambda | p value | Variance (%) | Cumulative (%) | Canonical correlation |
| Function 1 = −0.70 – 0.07 × α-tocopherol + 0.01 × γ-tocopherol + 0.035 × δ-tocopherol | 0.02 | 0.000 | 85.7 | 85.73 | 0.95 | Function 2 = −4.33 + 0.05 × α-tocopherol − 0.01 × γ-tocopherol + 0.11 × δ-tocopherol | 0.30 | 0.000 | 10.7 | 96.42 | 0.75 | Function 3 = −14.36 + 0.11 × α-tocopherol + 0.01 × γ-tocopherol + 0.01 × δ-tocopherol | 0.69 | 0.007 | 3.6 | 100.00 | 0.55 |
