From: Searching for differentially expressed gene combinations
Six examples of joint differential gene expression according to the on/off-scenario, obtained from the colon and BRCA1 data. The inner panels show the joint distribution; the outer margins display the univariate distributions. Blue triangles stand for cancerous and BRCA1 mutants, the red circles for normal and BRCA1 wild types, respectively. The dashed lines represent the direction of the conditional first principal components.
