Talk:Credible interval

From Wikipedia, the free encyclopedia

is credible interval random?

No.

A frequentist confidence interval is a RANDOM interval that contains a FIXED POINT a specified percentage of the time in repeated sampling.

A credible interval is a FIXED INTERVAL such that the values of a certain RANDOM VARIABLE fall within it with a specified probability.

or Yes ... it is possible to consider the frequency properties (coverage probabilities) of credibility intervals, in which case the ends of a credibility interval are treated as being random when considering the coverage probabilities (ie. via stochastic simulation studies). Of course the ends of the credibility region are treated as fixed when credibility intervals are interpreted as credibility intervals, whereas the ends of a confidence interval are treated as random when confidence intervals are interpreted as confidence intervals.
