Figure 4.
Line plots of the histograms for the observed distribution of Spearman expression distances (solid gray) and the simulated distribution under the assumption of random divergence (solid black). The probability density functions for each of the two truncated normal mixture model distributions are also shown at their mixture proportions (dashed). Parameters for the left mixture distribution were mean (μ1) = 0.3907, standard deviation (σ1) = 0.2470, mixture proportion (π1) = 0.5294. Parameters for the right distribution were μ2 = 0.9630, σ2 = 0.2944, and π2 = 0.4706.
