init.simulate.OU

Function used in <code><a href="/link/simulate?package=PhylogeneticEM&version=1.8.0" data-mini-rdoc="PhylogeneticEM::simulate">simulate</a></code> for OU initialization.

internal

Implementation of the automatic shift detection method for
Brownian Motion (BM) or Ornstein–Uhlenbeck (OU) models of trait evolution on
phylogenies. Some tools to handle equivalent shifts configurations are also
available. See Bastide et al. (2017) <doi:10.1111/rssb.12206> and
Bastide et al. (2018) <doi:10.1093/sysbio/syy005>.
