BEAST v2.7.8 Documentation: sa.evolution.speciation.ParameterizedSABirthDeathModel

BEASTObject that performs calculations based on the State.
Probabilistic representation that can produce a log probability for instance for running an MCMC chain.
Distribution on a tree, typically a prior such as Coalescent or Yule
A likelihood function for speciation processes.
Calculate tree density under Birth Death Sampling Through Time Model for Epidemics that is the BDM where an individual is sampled at a time with a constant rate psi and where an individual becomes noninfectious immediately after the samplingwith a constant probability r
