Like statistical data analysis more broadly, the main aim of Bayesian Data Analysis (BDA) is to infer unknown parameters for models of observed data, in order to test hypotheses about the physical processes that lead to the observations. As demonstrated above, the Bayesian framework is able to overcome many drawbacks of the classical t-test.
