Estimation of bottleneck parameters for European populations of . The data analyzed are described in [11]. The regression ABC was performed with both tangent [24] and logarithmic transformations [12]. In each panel, the solid line is the approximate posterior distribution obtained
using the regression-ABC algorithm and the natural-log transformation, the dotted
line is the result of regression-ABC using the transformation from [24], and the dot-dashed line are the rejection sampling results from [11]. The parameters are (a), Drosophila melanogastert_{r }the recovery time from the bottleneck, in units of 4N_{e }generations, (b) d, the duration of the bottleneck in units of 4N_{e }generations, and (c) f, the severity of the bottleneck, which is the ratio of the bottlenecked population
size to the pre-bottleneck population size.
