Bayesian testing

WebMar 24, 2016 · If we use Bayesian estimation/testing instead, having some prior (around 0?) for all comparisons, then yes the prior will shrink the posteriors toward zero, but we would still have randomly varying posteriors and/or Bayes factors and will probably have some cases out of 1000 that will look like "substantial" effects, even when true effects are ...

In the Bayesian … WebThe Bayes factor can be thought of as a Bayesian analog to the likelihood-ratio test, but since it uses the (integrated) marginal likelihood rather than the maximized likelihood, both tests only coincide under simple hypotheses (e.g., two specific parameter values). [2]

WebBecause the Bayes factor is comparing evidence for two hypotheses, it also allows us to assess whether there is evidence in favor of the null hypothesis, which we couldn’t do with standard null hypothesis testing (because it starts with the assumption that the null is true). WebNov 6, 2024 · First, Bayes factors can provide direct evidence for the common null hypothesis of no difference. 13 Second, they can reveal when experimental data is insensitive to the null and alternative hypotheses, clearly suggesting that the researcher should withhold judgment. 13 Third, they can be interpreted continuously and thus …
