Performs a Migration death move (Ewing et al. 2004). Selects an ancestral node
uniformly at random and removes the parent of the selected node, allocating
demes as necessary for modified edges.
Usage
migration_death(ED, n_deme, fix_leaf_deme = TRUE, node_indices)
Arguments
- ED
Extended data object; matrix with columns Node ID, parent, child 1, child 2, deme, node age
- n_deme
Number of distinct demes in the population
Value
Updated extended data object with the proposal from the migration death move
