Have you used Bayes factor to test point-null hypotheses in Hierarchical models and wondered: 1. Bridge sampling (BS) or Savage-Dickey density ratio (SDDR)? 2. If SDDR, which density estimation method? 3. How many MCMC samples? 4. What's the cost-benefit trade-off? This may be of interest to you.

How to best estimate Bayes factors for standard hypothesis tests? We compared bridge sampling and the Savage-Dickey density ratio. The latter does a good job in most constellations typical for experiments in cognitive psychology.

Reliability, bias, and computational cost of estimating the Bayes factor using bridge sampling and the Savage–Dickey density ratio - Behavior Research Methods

Bayes factors often require numerical estimation because closed-form solutions are unavailable. In six simulation studies, we explored the reliability, bias, and computational cost of two easy-to-use ...
