For the rationale behind Bayesian First Aid see the original announcement and the description of the alternative to the binomial test. We’ll start with the two most simple here follows the Bayesian First Aid alternatives to the one sample t-test and the paired samples t-test.īayesian First Aid is an attempt at implementing reasonable Bayesian alternatives to the classical hypothesis tests in R. The t-test comes in many flavors: one sample, two-sample, paired samples and Welch’s. To be honest, if I had to choose I would most of the time prefer a notched boxplot to a t-test. In comparison, “Bayesian” gives 130,000 hits while “box plot” results in only 12,500 hits. A quick search on Google Scholar for “t-test” results in 170,000 hits in 2013 alone. Student’s t-test is a staple of statistical analysis.
