FIG 4.

The sizes of branch rate 95% CIs from analyses under the DPP (•), GMC (□), and independent rates models (×) plotted against the true branch rates. Analyses were performed on data sets with substitution rate variation generated under six different models: (a) the GMC, (b) LMCs, (c) the CPP, (d) AR-LN, (e) IR-G, and (f) uncorrelated rates generated under the Dirichlet process. For each comparison, the true branch-specific rates were binned, so that each bin contained 100 rate values and the average 95% CI range was calculated for each bin.
