Bayesian Meta-Analysis with brms

In our previous post, Examining Meta Analysis, we contrasted a frequentist version of a meta analysis conducted with R’s meta package with a Bayesian meta analysis done mostly in stan using therstan package as a front end. In this post, we repeat the analysis using the brms package, which also depends on stan but allows the user to formulate complex Bayesian models without writing any stan code.

Dyson’s Algorithm for the Twelve Coins Problem

Puzzle Corner

The Twelve Coins Problem, a notoriously hard problem that comes in many flavors, was popular on both sides of the Atlantic during World War II; it was even suggested that it should be dropped over Germany in an attempt to sabotage their war effort.

The Perplexed Banker
