Comparing Models using Resampling and Bayesian Methods
Comparing Models using Resampling and Bayesian Methods


Nearly everyone is dissatisfied with classical statistical hypothesis testing approaches to comparing things. In this talk, a Bayesian method is described that uses model resampling statistics to make direct comparisons between models (i.e. no p-values). An example is shown to illustrate how to determine practical (!= statistical) differences in performance using the tidyposterior R package.
