I3 Bayesian parameter estimation with a binomial model example

Bayesian statistics uses Bayes' Rule to make decisions. In the context of a parametric model, parameters are updated from the prior using data to obtain the posterior using Bayes' Rule. From this posterior, Bayes' estimators and credible intervals can be obtained. The video discusses the posterior expectation and equal-tail credible intervals. As an example throughout, the video uses a binomial model with a uniform prior on the probability of success. The posterior is shown (but not derived) to be a beta distribution. A brief detour to discuss the beta distribution ensures. R code is provided to perform all of the Bayesian analyses for binomial data.
