Figure 2. RMSE for the estimate of divergence time (τ) as a function of the population mutation rate (θ), values of simulated migration rate (M₁₂ = M₂₁) and population recombination rate (ρ).

The RMSE is computed across 140 datasets with divergence time fixed at τ = 0.1. (a) For the four maximum likelihood methods (D₁–D₄) and MIMAR, (b) for the four composite-likelihood methods (J₁–J₄) and MIMAR.
