BEAST v2.5.0 Documentation: beast.math.distributions.MarkovChainDistribution

BEASTObject that performs calculations based on the State.
Probabilistic representation that can produce a log probability for instance for running an MCMC chain.
A class that produces a distribution chaining values in a parameter through the Gamma distribution. The value of a parameter is assumed to be Gamma distributed with mean as the previous value in the parameter. If useLogNormal is set, a log normal distribution is used instead of a Gamma. If a Jeffrey's prior is used, the first value is assumed to be distributed as 1/x, otherwise it is assumed to be uniform. Handy for population parameters.

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