aNo represents the number of components.
^b,c𝑅²𝑋_cum and 𝑅²𝑌_cum represent the cumulative sum of squares (SS) of all the 𝑋’s and 𝑌’s explained by all extracted components.
^d𝑄²𝑌_cum is an estimate of how well the model predicts the 𝑌’s.
^e1P + 2O: one predictive component and two orthogonal components for establishing the OPLS model.
