Webformal Bayesian tool to solve such problems is the Bayes factor (Kass and Raftery, 1995) that reports the evidence in the data favoring each of the entertained hypotheses/models … WebIn the example above the analysis prior was. β ∼ t s t u d e n t ( d f = 3, μ = 0, σ = 5) and the data generation prior was. β ∼ N ( μ = − 1, σ = 0.5). To conduct the Bayesian power analysis, I replicated the simulation and model fitting shown above 1000 times for each of seven different sample sizes ranging from 100 to 400.
