BEAST v2.7.8 Documentation: sa.evolution.operators.TreeDimensionJump

Proposes a move in state space.
This operator changes a beast.tree.
Implements a narrow move between trees of different dimensions (number of nodes in trees).It takes a random sampled node which is either a leaf with the younger siblingor a sampled internal node. In the first case, the leaf becomes a sampled internal node by replacing its parent (the height of the leaf remains unchanged). In the second case, the sampled internal node becomes a leaf by inserting a new parent node at a height which is uniformly chosen on the interval between the sampled node height and its old parent height.
