The current, nearly omnipresent, approach to hypothesis testing in all of the social sciences is a synthesis of the Fisher test of significance and the Neyman-Pearson hypothesis test. In this “modern” procedure, two hypotheses are posited: a null or restricted hypothesis (H0) which competes with an alternative or research hypothesis (H1) describing two complementary notions about some phenomeno...

In the classical approach to statistical hypothesis testing the role of the null hypothesis H0 and the alternative H1 is very asymmetric. Power, calculated from the distribution of the test statistic under H1, is treated as a theoretical construct that can be used to guide the choice of an appropriate test statistic or sample size, but power calculations do not explicitly enter the testing proc...
The Bayes factor is commonly used for assessing the evidence for or against a given hypothesis H0 : θ ∈ Θ0, where Θ0 is a subset of the parameter space. In this paper we discuss the Bayes factor and various issues associated with its use. A Bayes factor is seen to be intimately connected with a relative belief ratio which provides a somewhat simpler approach to assessing the evidence in favor o...
