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.

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 ...

Optimal Designs for the Rasch Model
Psychometrika, 2012In this paper, optimal designs will be derived for estimating the ability parameters of the Rasch model when difficulty parameters are known. It is well established that a design is locally D-optimal if the ability and difficulty coincide. But locally optimal designs require that the ability parameters to be estimated are known.

In Kap. 16 wurde das Rasch-Modell als ein Modell der Item-Response-Theorie vorgestellt. Da in Modellen der Item-Response-Theorie die Beziehungen zwischen den Losungswahrscheinlichkeiten einzelner Items und den Auspragungen einer latenten Variablen spezifiziert werden, eignen sich diese Modelle in besonderer Weise zur Selektion von Items fur ein ...

THE NATURE OF OBJECTIVITY WITH THE RASCH MODEL
Journal of Educational Measurement, 1974Although it has been claimed that the Rasch model leads to a higher degree of objectivity in measurement than has been previously possible, this model has had little impact on test development. Population‐invariant item and ability calibrations, together with the statistical equivalency of any two item subsets, are supposedly possible if the item pool ...

Responses to items with formats in more than two ordered categories are ubiquitous in education and the social sciences. Because the putative ordering of the categories reflects an understanding of what it means to have more of the variable, it seems ...

Residualanalysis in the Polytomous Rasch Model
Psychometrika, 1995Residuals for check of model fit in the polytomous Rasch model are examined. Comparisons are made between using counts for all response pattern and using item totals for score groups for the construction of the residuals. Comparisons are also, for the residuals based on score group totals, made between using as basis the item totals, or using the ...
