WebJul 23, 2024 · In general, the credible interval will be more precise because we are adding information or data. This can be seen more clearly if we look at the respective widths of the confidence and credible intervals, with the former being based only on m and the latter being divided by a larger number ( m + n0 ). WebMay 18, 2015 · An alternative method is to use a Bayesian approach (in which case, the interval estimate calculated is not a "confidence interval" but a "credible interval"). The idea is to treat the rate parameter λ as a random variable.
