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.
Yule prior with calibrated monophyletic clades. With this prior, the marginal distribution of the calibrated nodes (the MRCA of clades) is identical to the specified calibration, but the Yule is not preserved over the whole tree space, only among sub-spaces.

Logable: yes, this can be used in a log.

|Type of correction: none for no correction (same as BEAST1), full for Yule-like over calibrated times, and restricted for Yule-like over calibrated times and ranked topology (default 'full'). However, 'full' is generally slow except for in a few special cases, such as a single clade or two nested clades.|
