WebThe meaning of the Bayesian posterior is that given the actual result, the probability that $\pi=1/3$ is 3.35%. It is unlikely that it is the true value, but there is a small chance it is the actual value. Notice though that if you had not called the Mint, then your posterior probability would have been 4.47%. That is the subjective component. WebDec 14, 2001 · Bayesian inference takes a view of the phylogeny problem that makes analysis of large data sets more tractable: Instead of searching for the optimal tree, one samples trees according to their posterior probabilities.
