Composite likelihood ratio test and Goodness-of-fit test.

1Sites with missing or ambiguous information in the outgroup were excluded from this analysis.
L, number of nucleotides of the multiply alignment region; S, number of segregating sites; R, population recombination rate per nucleotide (in 2N units); SNM, standard neutral model; BN, bottleneck model; α strength of positive selection (in 2Ns units); X, location of the target of positive selection; GOF, goodness-of-fit test; n. a., not applicable. For the GOF test, probability values that do not support a better fit to the general alternative model than to the selective sweep model are indicated in bold.
