Assessing the Impact of Characteristics of the Test, Common-items, and Examinees on the Preservation of Equity Properties in Mixed-format Test Equating [PDF]
Preservation of equity properties was examined using four equating methods - IRT True Score, IRT Observed Score, Frequency Estimation, and Chained Equipercentile - in a mixed-format test under a common-item nonequivalent groups (CINEG) design.

Abstract Differential Item Functioning (DIF) analysis is used to identify potentially biased items in multi‐item measurements. In addition to testing the statistical significance, it is essential to evaluate the practical significance of DIF through effect size measures.

Assessing parameter invariance in item response theorys logistic two item parameter model: A monte carlo investigation [PDF]
Statistical properties of the ability level estimate (theta) in item response theory (IRT) were investigated through a Monte Carlo investigation, based on data generated with a four cases multifactor design.

lordif: An R Package for Detecting Differential Item Functioning Using Iterative Hybrid Ordinal Logistic Regression/Item Response Theory and Monte Carlo Simulations [PDF]
Logistic regression provides a flexible framework for detecting various types of differential item functioning (DIF). Previous efforts extended the framework by using item response theory (IRT) based trait scores, and by employing an iterative process ...

Mixture multigroup structural equation modelling for ordinal data
Abstract Social scientists often compare groups in terms of relations between latent variables (LV) (i.e. structural relations) using Structural Equation Modelling (SEM). LVs are measured indirectly by questionnaires; thus, measurement invariance must be evaluated before comparisons can be made. To efficiently compare many groups, the recently proposed

A Definition of a Heywood Case in Item Response Theory Based on Fisher Information
Heywood cases and other improper solutions occur frequently in latent variable models, e.g., factor analysis, item response theory, latent class analysis, multilevel models, or structural equation models, all of which are models with response variables ...

A MATLAB Package for Markov Chain Monte Carlo with a Multi-Unidimensional IRT Model [PDF]
Unidimensional item response theory (IRT) models are useful when each item is designed to measure some facet of a unified latent trait. In practical applications, items are not necessarily measuring the same underlying trait, and hence the more general ...
