WebJan 14, 2024 · One of the features that we have recently added to JASP is a Bayesian “A/B test”, that is, a test for the equality of two binomial proportions. This test is especially popular in the analysis of clinical trial data, where the proportion of medical successes (or failures) from a treatment group is contrasted against those from a control group. WebJan 20, 2014 · The Model. Coming up with a Bayesian alternative for the binomial test is almost a no-brainer. The data is a count of the successes and failures in some task (where what is labeled success is an arbitrary choice most of the time). Given this impoverished data (no predictor variables and no dependency between trials) the distribution for the … hindsight homestead
