Power to demonstrate evidence for the null-hypothesis with Bayes-Factor = 3 as criterion increased only slightly from 87% to 91%, but a sample size of N = 100 is sufficient to produce Bayes-Factors greater than 10 in favor of the null-hypothesis 52% … Web21 de jun. de 2024 · In general a Bayes factor is integrating out the uncertainty in the parameter. The priors quantify the uncertainty in the value of the parameter. In the code you have written where you integrate over the Binomial probability by placing a prior on the parameter p and integrating over that parameter. Both priors that you have written are …

Web13.1.1 A Bayesian one-sample t-test. A Bayesian alternative to a \(t\)-test is provided via the ttestBF function. Similar to the base R t.test function of the stats package, this function … The Bayes factor is a ratio of two competing statistical models represented by their evidence, and is used to quantify the support for one model over the other. The models in questions can have a common set of parameters, such as a null hypothesis and an alternative, but this is not necessary; for instance, it could also be a non-linear model compared to its linear approximation. The Bayes factor can be thought of as a Bayesian analog to the likelihood-ratio test, but since it uses the (in…
