bain is an abbreviation for BAyesian INformative hypothesis evaluation. It uses the Bayes factor to evaluate hypotheses in a wide variety of statistical models. One example are the hypotheses H1: m1 = m2 = m3, H2: m1 > m2 > m3, and Hu: m1, m2, m3 (no constraints) where m1, m2, and m3 denote the means in an ANOVA model. Another example is the hypothesis H1: b1 > 0, b2 > 0, b1 > b2 and its complement Hc: not H1, where b1 and b2 denote standardized regression coefficients.

Saarbrucken, 4 and 5 July 2019. Download the course materials HERE . Install de course materials in a folder on your laptop. Bring the laptop to the workshop with R, RStudio, and bain (in RStudio go to – tools – install packages) installed. Before the workshop familiarize yourself with R by reading and executing the R-hand-on-mini-course.pdf contained in the course materials. You can prepare further by reading BFTutorial.pdf.
