BEAST v2.7.8 Documentation: starbeast3.operators.CoordinatedExponential

Proposes a move in state space.


Implements a version of the co-ordinated species and gene tree operator described in Jones (2015).Specifically, this operator moves the species tree root node and a set of gene tree nodes related to thespecies tree node by a uniform amount chosen from an exponential distribution, offset to preserve thetopology of all trees. See http://dx.doi.org/10.1101/010199 for full details.
