Checking the Assumptions of Rasch's Model for Speed Tests

Peer reviewed

Direct link

Jansen, M. G. H.; Glas, C. A. W. – Psychometrika, 2005

Two new tests for a model for the response times on pure speed tests by Rasch (1960) are proposed. The model is based on the assumption that the test response times are approximately gamma distributed, with known index parameters and unknown rate parameters. The rate parameters are decomposed in a subject ability parameter and a test difficulty…

Constructing the Exact Significance Level for a Person-Fit Statistic.

Peer reviewed

Liou, Michelle; Chang, Chih-Hsin – Psychometrika, 1992

An extension is proposed for the network algorithm introduced by C.R. Mehta and N.R. Patel to construct exact tail probabilities for testing the general hypothesis that item responses are distributed according to the Rasch model. A simulation study indicates the efficiency of the algorithm. (SLD)
