When high-stakes decisions depend on test scores, it is natural to ask whether examinees' relative standing is determined by the response evidence or by the scoring rule. This paper characterizes when four IRT proficiency estimators-maximum...

We discuss two approaches to estimating the true score from classical test theory, each with a corresponding measure of uncertainty due to measurement error: the classical method with the standard error of measurement (SEM) and Kelley's met...

Categorical structural equation models (cat-SEM) typically rely on tetrachoric/polychoric correlations under a latent multivariate normality assumption. This can be generalized to an elliptical latent trait, whose radial symmetry justifies ...

In this paper, we introduce the Generalized Mixed Regularized Reduced Rank Regression model (GMR4), an extension of the GMR3 model designed to improve performance in high-dimensional settings. GMR3 is a regression method for a mix of numeri...

A model for multiple-choice (MC) items based on signal detection theory (SDT), the MC-SDT model (DeCarlo, 2021a), follows from assumptions about perceptual and decision processes involved when examinees choose alternatives for MC items. The...
Modular item response and structural equation modelling via measurement and uncertainty preserving parametric modelling [0.03%]

Latent variable item response and structural equation models are widely used to model constructs and acknowledge measurement error in research settings and operational assessments. Such work often proceeds in stages, where the results of an...
Approximating multidimensionality with asymmetric unidimensional IRT models [0.03%]

Xiangyi Liao et al.
Unidimensional item response theory (IRT) models are widely used even in settings where assessment data exhibit subtle forms of multidimensionality. Recent empirical evidence suggests that when item difficulty is associated with dimensional...
Composite marginal likelihood estimation of higher-order diagnostic classification models under high dimensionality [0.03%]

Although full-information maximum likelihood (FIML) estimation is widely used for diagnostic classification models (DCMs), its computational efficiency deteriorates sharply in high-dimensional settings. This scalability challenge is increas...
Refining the asymptotically correct standardization of person-fit statistics for mixed-format tests [0.03%]

Sinharay (Psychometrika, 2016, 81, 992) suggested the asymptotically correct standardized version of a class of person-fit statistics for mixed-format tests. This paper provides an alternative and arguably simpler derivation of the standard...

Study design and subsequent data analysis is ideally a collaborative endeavour between applied researchers and statistical experts (e.g. methodologists, data scientists). Applied researchers know what research questions need to be answered ...
