Stochastic and Historical Resonances of the Unit in Physics and Psychometrics

摘要

Humphry's article, "The Role of the Unit in Physics and Psychometrics," offers fundamental clarifications of measurement concepts that I hope will find a wide audience. In particular, parameterizing discrimination while preserving statistical sufficiency will indeed provide greater flexibility in accounting "for the effects of empirical factors on the unit of a scale" (p. 17).
