Figure 2

PCA sample scores of the datasets that were used in CCA analysis. PCA was applied to (a) the Gata3 dataset and (b) the Th dataset. Sample relationships (sample scores) of the first 3 axes are shown. Sample scores in 2D plots (b) are deliberately shown by arrows, in order to emphasise that these samples correspond to the explanatory variables that are shown by blue arrows in Figure 3. Percentage indicates that of the variance accounted for by the eigenvalue of the axis.
