present a discussion with Dr.Peter Killeen of the Department

"Decision
Theory for Statistical Inference in the Sciences: Beyond the nil Null"
| Abstract: I briefly review why Null hypothesis statistical tests (NHST) were a flawed solution to the problem of assigning a probability to a point statistic (e.g., a sample mean). I show why, under NHST, critical regions (alpha levels) should always be set to zero. I propose machinery for decision criteria (e.g., for publication) that incorporates both effect size and replicability. This last is in an early stage of development. |
