The Logical Consistency of Simultaneous Agnostic Hypothesis Tests
Simultaneous hypothesis tests can fail to provide results that meet logical requirements. For example, A implies B, there exist tests that, based on the same data, reject B but not A. This paper develops logically-coherent agnostic tests that also perform well statistically. These tests are characterized as region estimator-based tests.
