Figure 1From: Resolution of large and small differences in gene expression using models for the Bayesian analysis of gene expression levels and spotted DNA microarraysDetection of gene expression differences from ratio data that are truncated-ratio-of-normals distributed. Frequencies of affirmative significance calls with six analytical models are plotted against the factor of gene expression difference. Symbols represent the analysis model used: AC(+), AV(◇), AU(O), MC(×), MV(□), and MU(△). Diagrams correspond to data simulated with A) and B) equal variance in the two nodes of the experimental design, and C) and D) standard deviations proportional to expression level in each node.Back to article page
