# How to calculate corrected BF manually?

Hi all,

So I have run a Bayesian repeated measures ANOVA followed up with post-hoc tests (actually, the comparisons are planned, but nevertheless). JASP gives me uncorrected Bayes Factors, but I'd much prefer to report corrected Bayes Factors (given the number of tests that are performed). I assume there is a way I can calculate this using the prior odds and the corrected posterior odds; I am just not sure how (by now it is evident that I'm merely a pragmatic Bayesian). I've added the output, so if someone here could just show me how to do this for one of the postdoc test, I'd be happy!

Yes, this is based on the Westfall paper. If you send me an Email at EJ.Wagenmakers@gmail.com I can give you the thesis of Tim de Jong who explains how it's done.
