Jointly modeling responses and omitted items by a competing risk model: A survival analysis approach
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Item response theory models are commonly adopted in educational assessment and psychological measurement. Such models need to be modified to accommodate practical situations when statistical sampling assumptions are violated. Omission is a common phenomenon in educational testing.

Score‐based tests for parameter instability in ordinal factor models
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract We present a novel approach for computing model scores for ordinal factor models, that is, graded response models (GRMs) fitted with a limited information (LI) estimator. The method makes it possible to compute score‐based tests for parameter instability for ordinal factor models.

Another Look at Yen's Q3: Is .2 an Appropriate Cut‐Off?
Journal of Educational Measurement, EarlyView.Abstract This study examined the widely used threshold of .2 for Yen's Q3, an index for violations of local independence. Specifically, a simulation was conducted to investigate whether Q3 values were related to the magnitude of bias in estimates of reliability, item parameters, and examinee ability.

Unidimensionality in Rasch Models: Efficient Item Selection and Hierarchical Clustering Methods Based on Marginal Estimates [PDF]
arXiv, 2023 A strong tool for the selection of items that share a common trait from a set of given items is proposed. The selection method is based on marginal estimates and exploits that the estimates of the standard deviation of the mixing distribution are rather stable if items are from a Rasch model with a common trait.
