An Adaptive Design for Item Parameter Online Estimation and Q-Matrix Online Calibration in CD-CAT
Frontiers in Psychology, 2021 The implementation of cognitive diagnostic computerized adaptive testing often depends on a high-quality item bank. How to online estimate the item parameters and calibrate the Q-matrix required by items becomes an important problem in the construction ...

Effects of Initial Values and Convergence Criterion in the Two-Parameter Logistic Model When Estimating the Latent Distribution in BILOG-MG 3. [PDF]
PLoS ONE, 2015 Parameters of the two-parameter logistic model are generally estimated via the expectation-maximization algorithm, which improves initial values for all parameters iteratively until convergence is reached.

Learning Latent Parameters without Human Response Patterns: Item Response Theory with Artificial Crowds [PDF]
Conference on Empirical Methods in Natural Language Processing, 2019 Incorporating Item Response Theory (IRT) into NLP tasks can provide valuable information about model performance and behavior. Traditionally, IRT models are learned using human response pattern (RP) data, presenting a significant bottleneck for large ...

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 ...

Psych, 2023 A constituting feature of item response models is that item and person parameters share a latent scale and are therefore comparable. The Person–Item Map is a useful graphical tool to visualize the alignment of the two parameter sets.

A Penalty Approach to Differential Item Functioning in Rasch Models [PDF]
, 2012 A new diagnostic tool for the identification of differential item functioning (DIF) is proposed. Classical approaches to DIF allow to consider only few subpopulations like ethnic groups when investigating if the solution of items depends on the ...

Examining item compromise: an introduction to deterministic gated item response theory model (DGIRT)
Journal of Computer Adaptive Testing in Africa, 2023 The calibration of item parameters (difficulty, discrimination and guessing parameters) estimate may only consider the true and not the cheating abilities of examinees.
