Figure 1.

Relative error (estimated value divided by the true, simulated value) when estimating p_a, s_a, and their product p_as_a from simulated data plotted against the number of nucleotides subject to mutation. The bars indicate the interval between the 25% and the 75% quantile, with the point or line representing the median. The simulation parameters were p_a = 0.015 and s_a = 0.1.
