Using the two principal components and the CCl 4 -toxicity classification, the quadratic regression classifier was fit to estimate the coefficients β 0 through β 5 . Then the same eigenvectors, or projection estimated in the PCA, were applied to the left-out observation to estimate the first two principal components; note that this side-steps any potential prediction bias.

We computed a PCA based on the polished matrix of single hybridizations to show that the treatment groups were ordinated together (data not shown).
As seen in Figure 3, the proliferation cluster is relatively induced in the MDA PCa 2a and 2b cell lines, shows little change in LNCaP and LAPC-4, and is repressed in the androgen deprived LNCaP cell lines.
