Parameter estimation. Boxplots of posterior mean estimates of (a) α, (b) κ (c) θ, (d) l, (e) branch length of the 8th branch t8 (the one with the divergence point), and (f) branch length of the 12th branch t12. Each boxplot is based on 100 simulations, except (c) and (d), where posterior means of θ and l are only estimated for those simulations strongly supporting the divergence point. Results are grouped by simulated θ value as marked on the x-axis. There are five simulations per group, with simulated α decreasing 2.0, 1.0, 0.5, 0.1, 0.01. The arrangement is such that temporal rate variation is generally increasing from left to right. The estimates of α are logged before plotting to better show the variation in the smaller values. The location of the true value(s) of each parameter are marked by a + just right of its plot.
