  <dc:title>Identification of Dichotomous Differential Item Functioning
(DIF) using Angoff's Delta Plot Method</dc:title>
  <dc:title>R package deltaPlotR version 1.9</dc:title>
  <dc: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) &lt;doi:10.18637/jss.v059.c01&gt;).</dc:description>
