From: Orthogonal projections to latent structures as a strategy for microarray data normalization

Figure 2

Illustration of the array baseline difference. The first Y-orthogonal score vector to,1 is shown together with the average A values for each slide. The to,1 values (averaged per slide) are displayed using point-up, light gray triangles whereas the average A values are displayed using point-down, dark gray triangles. The Pearson correlation coefficient between the two series is 0.992, suggesting that the score vector captures an array bias.
