| Zusammenfassung: | abstract: four requirements to be met are basic to the validity of the rasch-model and its consequences such as specific objectivity or results independent of the sample. whereas most goodness-of-fit statistics concentrate on the assumptions of sufficiency and monotonicity more recently some tests have been suggested to prove unidimensionality and stochastic independence. this paper presents the axioms of the rasch-model and gives a discussion of the corresponding goodness-of-fit tests. additionally suggestions for graphical analyses are included. the attempt has been made to provide a survey on diagnostical aids for detecting failures of the rasch-model.; |
