Figure 2

Model fit quality assessed for the zero-inflated RVM. We plot the ratio of observed and predicted counts (y-axis) for repeats of lengths five to ten (x-axis). The horizontal whiskers represent the mean values for a selection of amino acids (A, Q, I, and L, as indicated by shades of grey). The vertical whiskers indicate uncertainty, showing the model standard deviation. More than 90% of all observations fall within 10% of the prediction (dotted horizontal lines). The dashed horizontal lines represent deviations by 25%. Comprehensive graphs for all amino acids are provided by Suppl. Fig. S2 in Additional File 1.
