In this chapter, it is shown that the problem of evaluating model fit can be solved within the framework of the general multinomial model, and it is shown how tests for this framework can be adapted to the Rasch model. Four types of tests are considered: generalized Pearson tests, likelihood ratio tests, Wald tests, and likelihood ratio tests.

Conditions for Rasch-Dichotomizability of the Unidimensional Polytomous Rasch Model
Psychometrika, 1989Jansen and Roskam (1986) discussed the compatibility of the unidimensional polytomous Rasch model with dichotomization of the response continuum. They derived a rather strict condition in which dichotomization of multicategory data that fit the unidimensional polytomous Rasch model, results in dichotomous data which fit the dichotomous Research model ...

Over the past few years, several studies have investigated and demonstrated the relationships between generalized linear mixed models (GLIMM) and item response modeling. Some benefits associated with this GLIMM-based modeling framework include the modeling of nested structure of data, such as examinees nested within schools (Kamata, 2001), of ...

A New Derivation of the Rasch Model
1984Abstract The Rasch model is usually derived from statistical requirements of estimation of its parameters. The principle of 'specific objectivity' or, equivalently, 'sample independence' requires that subject parameters can be estimated independent from the item parameters and vice versa. This in turn requires that sufficient statistics exist for the

MISUNDERSTANDING THE RASCH MODEL
Journal of Educational Measurement, 1977Whitely and Dawis (1974) recently discussed, in this journal, the nature of objectivity with the Rasch model. They made several good points. However, their paper contained some unfortunate misunderstandings and errors. One important misunderstanding concerns the estimation procedure necessary to calibrate items according to the Rasch model. The authors

Journal of Early Intervention, 1992
The Rasch scaling model has been used to advance the development and application of tests in various fields including education, medicine, and psychology. The Rasch model has the potential for overcoming several problems which currently plague developmental measures in early intervention.

Multilevel Rasch Modeling: Does Misfit to the Rasch Model Impact the Regression Model?
The Journal of Experimental Education, 2019Multilevel Rasch models are increasingly used to estimate the relationships between test scores and student and school factors.

Derivations of the Rasch Model
1995Chapters 1 and 3 through 6 describe a number of especially attractive features of the Rasch model (RM). These assets - in particular, sufficiency of the unweighted raw score, existence of conditional maximum likelihood estimators of the model parameters and of conditional likelihood ratio tests for hypothesis testing - suggest the question as to ...

This Chapter explains the Rasch model for ordered response categories by demonstrating the latent response structure and process compatible with the model. This is necessary because there is some confusion in the interpretation of the parameters and the possible response process characterized by the model.

Einführung in das Rasch-Modell
1993In diesem Kapitel wird mit dem Rasch-Modell (nach dem danischen Mathematiker Georg Rasch) ein stochastisches Mesmodell der Item-Response-Theorie (IRT) vorgestellt, das zur Analyse von Variablen, die nur 2 verschiedene Werte annehmen konnen, verwendet werden kann Im Falle solcher zweiwertiger (dichotomer) Variablen sind das Modell essentiell τ ...
