A non-parametric Bayesian diagnostic for detecting differential item functioning in IRT models

Abstract

Differential item functioning (DIF) in tests and multi-item surveys occurs when a lack of conditional independence exists between the response to one or more items and membership to a particular group, given equal levels of proficiency. We develop an approach to detecting DIF in the context of item response theory (IRT) models based on computing a… (More)
