Experimental data fit: distributions. The three data ensembles from Ref.  [2] (histograms) with the corresponding theoretical fitting distributions (lines). Colors refer to epigenetics: red for active, black for inactive and blue for repressed domains. The theoretical distributions have been calculated from the analytical expression of the probability density by using the fitting parameters of Table 3. A more detailed view of the complete set of histograms and fits is given in Additional file 1: Figs. S6, S7 and S8
