The Polytomous Rasch Model within the Class of Generalized Linear Symmetry Models

摘要: Polytomous Rasch models are derived from a new requirement for objective measurement, the (quasi-)interchangeability of measurement instruments. This principle is introduced as symmetry restriction on statistical distribution set measurements. The formulated generalized linear model. An interesting property this that it does not assume conditionally independent item responses. related to assumption model: model shown be equivalent conditional or (extended) model; if local independence added, closely original
