A Conditional Item-Fit Index for Rasch Models [PDF]
Applied Psychological Measurement, 1994 A new item-fit index is proposed that is both a descriptive measure of deviance of single items and an index for statistical inference. This index is based on the assumptions of the dichotomous and polytomous Rasch models for items with ordered ...

Q-Matrix Refinement Based on Item Fit Statistic RMSEA. [PDF]
Appl Psychol Meas, 2019 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 ...

THE CORRELATION BETWEEN ITEM PARAMETERS AND ITEM FIT STATISTICS [PDF]
ETS Research Report Series, 2007 ABSTRACTDodeen (2004) studied the correlation between the item parameters of the three‐parameter logistic model and two item fit statistics, and found some linear relationships (e.g., a positive correlation between item discrimination parameters and item fit statistics) that have the potential for influencing the work of practitioners who employ item ...

Assessing Item-Level Fit for the DINA Model [PDF]
Applied Psychological Measurement, 2015 This research focuses on developing item-level fit checking procedures in the context of diagnostic classification models (DCMs), and more specifically for the “Deterministic Input; Noisy ‘And’ gate” (DINA) model. Although there is a growing body of literature discussing model fit checking methods for DCM, the item-level fit analysis is not adequately ...
