  1. Simulations were based on combined mtDNA and NRY sequences and the model of population history shown in Figure 1. Also shown are various statistics related to 1,000 pseudo-observed parameter estimations: R2 is the proportion of the variance in the parameters explained by the summary statistics; Bias indicates whether the parameter tends to be over-estimated (positive bias) or under-estimated (negative bias); RMSE (root mean square error) is a distance between the true and estimated values of the parameter.
