Description Usage Arguments Details Value Author(s) Examples
This function estimates the posterior probability that event 'a' is older than event 'b' using the output of the MCMC algorithm. This provides a bayesian test for checking the following assumption: "Event a is older than event b"

|
a_chain |
numeric vector containing the output of the MCMC algorithm for the first one-parameter (date) a |
b_chain |
numeric vector containing the output of the same MCMC algorithm for the second one-parameter (date) b |
For a given output of MCMC algorithm, this function estimates the posterior probability of the event 'a' < 'b' by the relative frenquency of the event "the value of event 'a' is lower than the value of event 'b'" in the simulated Makov chain.
Returns the posterior probability of the following assumption: "Event a is older than event b"
