... The posterior probabilities will still sum ( integrate) to 1 even if the prior values do not, and so the priors only need be specified in the correct proportion. In many cases the sum or integral of the prior values may not even need to be finite to get sensible answers for the posterior probabiliti ...

Probability models often assume independence when the random variables describe outcomes that appear unrela ...
