Webbrms::hypothesis: 14.1 (whoa!) brms::bayes_factor: 3.7; Three of them are in the same ballpark. While their small differences are likely due to differences in priors. bmrs::hypothesis is erroneous in this case as explained in that section above. In general, though, Savage-Dickey works well for models with more well-defined priors (normal, etc.). WebThe function brms::hypothesis can test the relevant hypotheses based on the brms_fit object stored in fit_brms_politeness.
