Figure 7

Correlation between diagnostics and bias of the MK statistics. Each point in the plot represents a single simulation replicate with the value of bias of ${â}_F$ (left column) and${â}_B$(right column) indicated by the colour of the point. Results are shown for u=10⁻⁶ (top row) and u=10⁻⁵(bottom row), and each panel consists of 100 replicates from all combinations of recurrent sweeps with τ=10³,10⁴, s _b =10⁻³,10⁻²and β=0.25,0.5,1,2. Simulations with bias outside the range of the colour scale were set at the extreme values and points with less than two medium frequency polymorphisms were excluded.
