What is a 95% credible interval?
Interpretation of the Bayesian 95% confidence interval (which is known as credible interval): there is a 95% probability that the true (unknown) estimate would lie within the interval, given the evidence provided by the observed data.

What is a good credible interval?
Examples of Credible Intervals If the subjective probability that the birthweight β is somewhere between 2.8 kgs and 3.5 is 90 %, we can say that 2.8 ≤ β ≤ 3.5 is a 90% credible interval.

How do you determine a credible interval?
To build credible interval, we simply truncate a left tail, or a right tail, or both, from the posterior distribution, so that the remaining probability mass (called “plausibility”) is as desired. For example, we can truncate 5% from either tail, and get a 90% credible interval [0.436, 0.865]:

What is a credible interval in statistics?
In Bayesian statistics, a credible interval is an interval within which an unobserved parameter value falls with a particular probability. It is an interval in the domain of a posterior probability distribution or a predictive distribution. The generalisation to multivariate problems is the credible region.
As the Bayesian inference returns a distribution of possible effect values (the posterior), the credible interval is just the�...

Feb 24, 2018If you find out that the 95% credible interval for your statistics final score is 70 to 90, this means you have a 95% chance of having a�...
For instance, the 95% credible interval is simply the central portion of the posterior distribution that contains 95% of the values.

A 95% confidence interval by definition covers the true parameter value in 95% of the cases, as you indicated correctly. Thus, the chance that�...
Confidence intervals vs credible intervals. ▷ A confidence interval is constructed to contain θ a percentage of the time, say 95%.
For a 95% credible interval, the value of interest (e.g. size of treatment effect) lies with a 95% probability in the interval. This interval is then open to�...
Given the observation Y=y, the interval [a,b] is said to be a (1−α)100% credible interval for X, if the posterior probability of X being in [a,b] is equal�...
