Bayesian $t$ tests have become an increasingly popular alternative to null-hypothesis significance testing (NHST) in psychological research. In contrast to NHST, they allow for the quantification of evidence in favor of the null hypothesis and for optional stopping. A major drawback of Bayesian $t$ tests, however, is that error probabilities of statistical decisions remain uncontrolled. Previous ...
