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".
: Numeric vector containing the output of the MCMC algorithm for the first parameter.
: Numeric vector containing the output of the MCMC algorithm for the second parameter.
For a given output of MCMC algorithm, this function estimates the posterior probability of the event 'a' < 'b' by the relative frequency of the event "the value of event 'a' is less than the value of event 'b'" in the simulated Markov chain.
An unnamed vector with the posterior probability of the assumption: "event a is older than event b"
