Abbreviation: COI, Cytochrome c Oxidase I.
SSD tests the validity of a sudden expansion model based on the sum of squares deviations between the observed and expected mismatch. Non-significant values for SSD signify that the data do not deviate from that expected under the model of expansion. Raggedness index is calculated similarly, and non-significant raggedness values also indicate population expansion.
n.a., least square procedure to fit model mismatch distribution and observed distribution did not converge.
