Web42 minutes ago · Just as, for example, posterior intervals and confidence intervals coincide in some simple examples but in general are different: lots of real-world posterior intervals don’t have classical confidence coverage, even in theory, and lots of real-world confidence intervals don’t have Bayesian posterior coverage, even in theory.

First, the coverage probabilities are in general not equal to the nominal level of confidence — namely .95. Moreover, coverage probabilities near and are effectively zero. Finally, the coverage probability function is discontinuous.
