Analysis This app computes the Bayesian posterior central interval for binomially distributed data (e.g., hit/miss, success/fail outcomes). We offer three approaches for computing the posterior central interval. Two approaches are based on the use of objective, or noninformative priors. A third approach allows the user to enter a subjective prior based on historical data. Bayesian Binomial Credible Intervals Interactive Shiny App
