Root mean square coalescent log odds
rmsclo.RdThis is a summary statistic that describes the amount of variation in coalescent rates across lineages in a phylogenetic tree It is defined as $$ \sqrt{ \sum_i l_i \psi_i^2 / L } $$ where the sum is over all branches i in the tree and weighted by branch length \(l_i\) and where \( L = \sum_i l_i \)
