Title: | A local-influence-based diagnostic approach to a speeded item response theory model | Authors: | Goegebeur, Yuri De Boeck, Paul MOLENBERGHS, Geert del Pino, Guido |
Issue Date: | 2006 | Source: | JOURNAL OF THE ROYAL STATISTICAL SOCIETY SERIES C-APPLIED STATISTICS, 55(5). p. 647-676 | Abstract: | An item response theory model for dealing with omitted responses in a test is proposed. In this model formulation, non-response does not only depend on an examinee's ability and on item difficulty, but additionally also on 'test speededness'. Using a local-influence-based diagnostic approach, the sensitivity of the model regarding assumptions concerning the drop-out mechanism is explored. The methodology proposed is applied to the Chilean Sistema de Medicion de la Calidad de la Educacion mathematics test case-study. | Keywords: | item response theory; local influence; missing data; ‘test speededness’;item response theory; local influence; missing data; 'test speededness'; PARAMETER-ESTIMATION; DEPENDENCE; PERFORMANCE; TESTLETS; TESTS; FIT | Document URI: | http://hdl.handle.net/1942/1474 | Link to publication/dataset: | https://ppw.kuleuven.be/okp/_pdf/Goegebeur2006ALIBD.pdf | ISSN: | 0035-9254 | e-ISSN: | 1467-9876 | DOI: | 10.1111/j.1467-9876.2006.00558.x | ISI #: | 000241390200006 | Rights: | © 2006 Royal Statistical Society | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2007 |
