  <dc:title>Income Polarization Index</dc:title>
  <dc:title>R package DER version 1.5</dc:title>
  <dc:description>Extremely fast and memory efficient computation of the DER (or PaF) income polarization index as proposed by Duclos J. Y., Esteban, J. and Ray D. (2004). "Polarization: concepts, measurement, estimation". Econometrica, 72(6): 1737--1772. &lt;doi:10.1111/j.1468-0262.2004.00552.x&gt;. The index may be computed for a single or for a range of values of the alpha-parameter and bootstrapping is also available. </dc:description>
