Comparison between NormFinder and ML-mixed model. Comparison between NormFinder and ML-mixed model 3 estimates of inter- and intra-group variability. Inter-group variation is represented in the Y axes. Intra-group variation (bias from our ML-mixed model procedure and intra-group standard deviations from the NormFinder one) is presented as error bars on estimates of the inter-group differences for each gene. Downward dotted bars correspond to NormFinder estimates and upward solid bars to ML-mixed model 3.
