How to Calculate Bayesian Credibility Intervals
APPENDIX
The calculation of credibility intervals assumes that Y has a binomial distribution conditioned on the
parameter θ, i.E., Y|θ~bin(n,θ), where n is the size of our sample. In this setting, Y counts the number
of “yes”, or “1”, observed in the sample, so that the sample mean ( ത𝑌) is a natural estimate of the true
population proportion θ. This model is often called the likelihood function, and it is a standard concept
in both the bayesian and the classical framework. The bayesian1 statistics combines both the prior
distribution and the likelihood function to create a posterior distribution.
The posterior distribution represents our opinion about which are the plausible values for θ adjusted
after observing the sample data. In reality, the posterior distribution is one’s knowledge base updated
using the latest survey information. For the prior and likelihood functions specified here, the posterior
distribution is also a beta distribution (π(
𝜃
𝑦
)~β(y+a,n-y+b)), but with updated hyper-parameters.
Our credibility interval for θ is based on this posterior distribution. As mentioned above, these intervals
represent our belief about which are the most plausible values for θ given our updated knowledge base.
There are different ways to calculate these intervals based on π (
𝜃
𝑦
). Since we want only one measure of
precision for all variables in the survey, analogous to what is done within the classical framework, we will
compute the largest possible credibility interval for any observed sample. The worst case occurs when
we assume that a=1 and b=1 and y=n/2. Using a simple approximation of the posterior by the normal
distribution, the 95% credibility interval is given by, approximately: ഥ𝑌 ∓
1
𝑛

FOR THIS POLL
The Bayesian credibility interval was adjusted using standard weighting design effect 1+L=1.3 to account for complex weighting2
