Inferential Item-Fit Evaluation in Cognitive Diagnosis Modeling [PDF]
Research related to the fit evaluation at the item level involving cognitive diagnosis models (CDMs) has been scarce. According to the parsimony principle, balancing goodness of fit against model complexity is necessary. General CDMs require a larger sample size to be estimated reliably, and can lead to worse attribute classification accuracy than the ...

Q-Matrix Refinement Based on Item Fit Statistic RMSEA [PDF]
A Q-matrix, which reflects how attributes are measured for each item, is necessary when applying a cognitive diagnosis model to an assessment. In most cases, the Q-matrix is constructed by experts in the field and may be subjective and incorrect. One efficient method to refine the Q-matrix is to employ a suitable statistic that is calculated using ...

A Comparison of Item- and Person-Fit Methods of Assessing Model-Data Fit in IRT [PDF]
Many item-fit statistics have been proposed for assessing whether the responses to test items ag gregated across examinees conform to IRT test models. Conversely, person-fit statistics have been proposed for assessing whether an examinee's re sponses aggregated across items are congruent with a specified IRT model.

Entropy-Based Measures for Person Fit in Item Response Theory [PDF]
This article introduces three new variants of entropy to detect person misfit ( E i , EM i , and EMR i ), and provides preliminary evidence that these measures are worthy of further investigation.
