Expression ranks of stable genes are preserved relative to each other. (A) Pairwise rank consistency measured as the proportion of samples where the expected ranks learned from the training datasets matches the observed rank. The gene-wise rank consistency is then the average of a gene's pairwise consistencies. The gene-wise consistency of HNRNPK is 1 indicating that its rank relative to the six other stable genes being considered is as expected (higher than the other genes in all samples). (B) Median gene-wise rank consistencies plot for stable genes from lists of sizes 5–30. Bands represent the inter-quartile range. Rank consistency is low in blood datasets due to reduced stability.
