Practical Consequences of Item Response Theory Model Misfit in the Context of Test Equating with Mixed-Format Test Data [PDF]
Frontiers in Psychology, 2017 In item response theory (IRT) models, assessing model-data fit is an essential step in IRT calibration. While no general agreement has ever been reached on the best methods or approaches to use for detecting misfit, perhaps the more important comment based upon the research findings is that rarely does the research evaluate IRT misfit by focusing on ...
