Estimation of bottleneck parameters for European populations of Drosophila melanogaster. The data analyzed are described in . The regression ABC was performed with both tangent  and logarithmic transformations . 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 , and the dot-dashed line are the rejection sampling results from . The parameters are (a), tr the recovery time from the bottleneck, in units of 4Ne generations, (b) d, the duration of the bottleneck in units of 4Ne generations, and (c) f, the severity of the bottleneck, which is the ratio of the bottlenecked population size to the pre-bottleneck population size.
