Bayesian t-tests

A lot of people want to understand more about Bayesian methods. Some people might get some traction by directly comparing something they already understand (such as a t-test) under the traditional approach, to a Bayesian way of tackling the problem.

John Kruschke comes to the rescue. He has published a nice paper on the Bayesian t-test, and hist website has a page of useful resources. Personally, I would recommend first watching Kruschke’s informative youtube video (below) and then trying a free online Bayesian t-test app.

If you are interested, then I highly recommend Kruschke’s book, Doing Bayesian Data Analysis (Amazon link), and has an info page here, and an interesting cover…
