      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hey Nico,&lt;/P&gt;&lt;P&gt;There might be different ways to do it. Here is one: &lt;A _jive_internal="true" class="active_link" href="https://communities.sas.com/message/243330#243330"&gt;https://communities.sas.com/message/243330#243330&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Good luck!&lt;/P&gt;&lt;P&gt;-Miguel&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hello Miguel! thanks for your answer..&lt;/P&gt;&lt;P&gt;I have not been able to resolve. There is a node or output table that shows me directly the correlation between the variables?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Te escribo esto en español ya que veo que sos latino igual que yo. El problema que estoy teniendo es que estoy construyendo un modelo de credit scoring, pero SAS no me toma como variables significativas unas X que para nosotros son FUNDAMENTALES, entonces lo que queremos es ver la correlación entre las variables, para así poder excluir las variables que tengan una correlación muy alta con las X que consideramos fundamentales, por mas que la significación global disminuya un poco.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hola Nico,&lt;/P&gt;&lt;P&gt;Español está bien, pero no juzgues mi ortografía, de acuerdo?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;En este tip (&lt;A _jive_internal="true" href="https://communities.sas.com/docs/DOC-11184"&gt;How to build a credit scorecard&lt;/A&gt;) comentaba que la forma ideal de reintroducir variables importantes en tu Scorecard es ajustar manualmente el Weight of Evidence.&lt;/P&gt;&lt;P&gt;Nota que antes de ajustarla manualmente el IV era de menos de 0.1 y quedaba excluída del Scorecard. Después de ajustar el WoE basado en conocimiento del negocio, hasta que quedó con IV mayor de 0.1. Otra alternativa es mover el Information Value cutoff en el Interactive Grouping node (lo encuentras en las propiedades de Score casi hasta abajo).&lt;/P&gt;&lt;P&gt;&lt;IMG alt="ign_manual woe.png" class="jive-image-thumbnail jive-image" src="https://communities.sas.com/legacyfs/online/11034_ign_manual woe.png" width="450" /&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;No obstante, si aún quieres ver la matriz de correlación, ve este &lt;A href="http://www2.sas.com/proceedings/forum2008/145-2008.pdf"&gt;paper &lt;/A&gt;(página 7-9). Tienen un muy buen ejemplo que hace justo eso.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Saludos!&lt;/P&gt;&lt;P&gt;-Miguel&lt;/P&gt;&lt;P&gt;---&lt;/P&gt;&lt;P&gt;summary in English&lt;/P&gt;&lt;P&gt;There is a best practice to reintroduce a variable that does not meet the cutoff for information value or gini. Override the WoE as described in this tip: &lt;A _jive_internal="true" href="https://communities.sas.com/docs/DOC-11184"&gt;How to build a credit scorecard&lt;/A&gt;.&lt;/P&gt;&lt;P&gt;If you still want to produce a correlation matrix,&lt;A href="http://www2.sas.com/proceedings/forum2008/145-2008.pdf"&gt; this paper &lt;/A&gt;describes how to do it with a SAS Code Node. Look at pages 7-9.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
