Figure 2From: Is this the right normalization? A diagnostic tool for ChIP-seq normalizationDistributions of estimated log relative risks. The empirical density of the log relative risks for background read counts that are distributed as Poisson (solid black); or as over-dispersed Poisson with p=0.5 (dot-dashed pink) and with p=0.25 (dash blue). The solid vertical line is l o g(r), with r=0.7. The peak is around logr for all three densities.Back to article page
