Cognitive Constructivism, Eigen-Solutions, and Sharp Statistical Hypotheses
In this paper epistemological, ontological and sociological questions concerning the statistical significance of sharp hypotheses in scientific research are investigated within the framework provided by Cognitive Constructivism and the FBST (Full Bayesian Significance Test). The constructivist framework is contrasted with the traditional epistemological settings for orthodox Bayesian and freque...
متن کاملDecoupling, Sparsity, Randomization, and Objective Bayesian Inference
Decoupling is a general principle that allows us to separate simple components in a complex system. In statistics, decoupling is often expressed as independence, no association, or zero covariance relations. These relations are sharp statistical hypotheses, that can be tested using the FBST Full Bayesian Significance Test. Decoupling relations can also be introduced by some techniques of Design...

متن کاملConstructive Verification, Empirical Induction, and Falibilist Deduction: A Threefold Contrast
This article explores some open questions related to the problem of verification of theories in the context of empirical sciences by contrasting three epistemological frameworks. Each of these epistemological frameworks is based on a corresponding central metaphor, namely: (a) Neo-empiricism and the gambling metaphor; (b) Popperian falsificationism and the scientific tribunal metaphor; (c) Cogn...
