Inference of α (proportion of beneficial substitutions), ϵ (rate of ancestral error), and DFE parameters: (mean selection coefficient of deleterious mutations), b (shape of distribution of deleterious DFE), (proportion of beneficial mutations), and (mean selection coefficient of beneficial mutations). The figure shows the inference quality for three simulated DFEs (Table 1) with different α values. The DFEs differ only in the simulated value of A full DFE is inferred from both polymorphism and divergence data, and ϵ is set to zero and is not estimated, or is estimated. The data were simulated with
