A Comparison of EoS values with Prior Work. Comparison of the EoS value with the ${\chi }_1^2$ statistics of prior work. (A) A per-site comparison of EoS values (left, red) with ${\chi }_1^2$ statistics (blue, right). Both values are plotted such that larger values roughly indicate 'greater significance'. (B) EoS and ${\chi }_1^2$ values are highly though non-linearly correlated, but are not comparable in terms of 'significance'. Specifically, while only 10/266 sites exceed the ${\chi }_1^2$ critical value of p < 0.05 as shown by the blue horizontal line, 41/266 sites showed a posterior odds ratio of 20:1 or greater as shown by the red vertical line. We emphasize that binning adjacent sites would increase the specificity of the χ² statistic at the cost of considerable sensitivity as per Behrsin et al. [7], and that 20:1 odds ratios are only roughly comparable to p values of 0.05.
