Figure 5-10 Superimposed density plots of the permutation tests on the datasets of case study 2<br />

using PLS-DA and nonlinear (RBF) SVMs<br />

The figure provides a visual comparison of the permutation distributions when different classification<br />

models are applied on the datasets of case study 2; the distributions for PLS-DA and SVMs are<br />

depicted in a semi-transparent blue and red colour respectively. In these plots, the dashed lines<br />

represent the mean values of each density curve and are coloured accordingly. By superimposing the<br />

density plots, major differences in the shape, spread and location of the distributions can be identified.<br />
