Anchor selection strategies for DIF analysis: Review, assessment, and new approaches [PDF]

, 2013
Differential item functioning (DIF) indicates the violation of the invariance assumption for instance in models based on item response theory (IRT). For item-wise DIF analysis using IRT, a common metric for the item parameters of the groups that are to ...

Potential application of item-response theory to interpretation of medical codes in electronic patient records [PDF]

, 2011
Background: electronic patient records are generally coded using extensive sets of codes but the significance of the utilisation of individual codes may be unclear. Item response theory (IRT) models are used to characterise the psychometric properties of

Regularized Generalized Logistic Item Response Model

Information, 2023
Item response theory (IRT) models are factor models for dichotomous or polytomous variables (i.e., item responses). The symmetric logistic or probit link functions are most frequently utilized for modeling dichotomous or polytomous items. In this article,
