Figure 4From: Different effects of the probe summarization algorithms PLIER and RMA on high-level analysis of Affymetrix exon arraysDistribution of Pearson correlation coefficients. The Pearson correlation coefficient between the mean exon expression level and the absolute difference in exon expression (between the two sample groups under consideration) was computed using PLIER-summarized data for each gene.
