An independent-samples Bayesian t-test with a default two-sided Cauchy prior on effect size yields the following result: The results show that 95% of the posterior mass under H1 falls in the interval from -0.503 to 0.233, well inside the default Cauchy’s interquartile range (i.e., [−.707,+.707]). WebThis page implements an online version of John Kruschke's Bayesian estimation supersedes the t-test (BEST), a Bayesian model that can be used where you classically would use a two-sample t-test.
