SYMMETREE: whole-tree analysis of differential diversification rates.

UNLABELLED: SymmeTREE implements several tests of differential diversification rates that exploit information on the topological distribution of species diversity throughout entire trees to address two general questions: (1) Has a given tree experienced significant variation in diversification rates among its branches? and (2) If so, along which branches have significant shifts in diversification rate occurred? These explicitly model-based methods are robust to uncertainty in estimates of branch length/duration and can accommodate incompletely resolved trees and other forms of phylogenetic uncertainty.
