Table 2.

The parameters of the OPLS-DA model.

Component R2X (cum) R2Y (cum) Q2Y (cum)
ESI+ mode 4P+1O 0.329 0.984 0.801
ESI− mode 5P+1O 0.434 0.993 0.796

R2X (cum) and R2Y (cum) represent the cumulative modeled variation in X and Y matrices, respectively, and Q2Y (cum) is the cumulative predicted variation. 4P+1O, four predictive components and one orthogonal component for establishing the OPLS-DA model in the ESI+ mode. 5P+1O, five predictive components and one orthogonal component for establishing the OPLS-DA model in the ESI− mode.
