deltaPlotR

Identification of Dichotomous Differential Item Functioning (DIF) using Angoff's Delta Plot Method

v1.6 · Mar 16, 2018 · GPL (>= 2)

Description

The deltaPlotR package implements Angoff's Delta Plot method to detect dichotomous DIF. Several detection thresholds are included, either from multivariate normality assumption or by prior determination. Item purification is supported (Magis and Facon (2014) <doi:10.18637/jss.v059.c01>).
