Bridge-PLSR scores. The two first Bridge-PLSR score-vectors describing the smoker-data are plotted. These components account for 54% of the (calibrated) variance of Y, but only 11% of the X-variance is explained by the model. The first component distinguishes well between current and never smokers, while the second component spans the minute variation that separates former smokers from the rest.
