WebJul 5, 2024 · Details. The Bayes factor provided by ttestBF tests the null hypothesis that the mean (or mean difference) of a normal population is mu0 (argument mu).Specifically, the Bayes factor compares two hypotheses: that the standardized effect size is 0, or that the standardized effect size is not 0.
