OptM: Estimating the Optimal Number of Migration Edges from 'Treemix'
The popular population genetic software 'Treemix' by
'Pickrell and Pritchard' (2012) <doi:10.1371/journal.pgen.1002967>
estimates the number of migration edges on a population tree.
However, it can be difficult to determine the number of migration
edges to include. Previously, it was customary to stop adding migration
edges when 99.8% of variation in the data was explained, but 'OptM'
automates this process using an ad hoc statistic based on the
second-order rate of change in the log likelihood. 'OptM' also
has added functionality for various threshold modeling
to compare with the ad hoc statistic.
