Title:
Uniformly most powerful Bayesian tests and the reproducibility of scientific research

Abstract:
Uniformly most powerful Bayesian tests are defined and compared to classical uniformly most powerful tests. By equating the rejection 
regions of these two tests, an equivalence between Bayes factors based on these tests and frequentist p-values is illustrated. The implications of this equivalence for the reproducibility of scientific research are examined. Approximately uniformly most powerful Bayesian tests are described for t tests, and the power of these tests are compared to ideal Bayes factors (defined by determining the best test alternative for each true value of the parameter), as well as to Bayes factors obtained using the true parameter value as the alternative. 
Interpretations and asymptotic properties of these Bayes factors are also discussed.
