Canonical Bayesian Psychometric Modeling

We now pivot from foundational issues that comprised the first half of the book to focus on psychometrics. We begin by introducing what we refer to as the canonical psychometric model, an abstraction of the popular psychometric models that are the foci of the second half of the book. We develop Bayesian approaches to common psychometric activities in the context of this model. We consider these approaches to be canonical as well, and they will shape much of the rest of this book. After introducing them, we briefly discuss the extent to which these approaches are prevalent in operational assessment. We conclude with a summary discussion that looks ahead to the rest of the book. The treatment is abstract ...
