      <title>select test control BEFORE the experiment</title>
      <link>https://communities.sas.com/t5/SAS-Programming/select-test-control-BEFORE-the-experiment/m-p/675614#M203580</link>
      <description>&lt;P&gt;Hi SAS community,&amp;nbsp;&lt;/P&gt;&lt;P&gt;I know how to do matching if there is already a test group set up.&amp;nbsp;&lt;/P&gt;&lt;P&gt;But if we are trying to select test/control group before the intervention happens, what code do I use? the idea is to select comparable 1:1 cohorts and randomize one to test and one to control. The variables we are trying to control for are demographic, access to internet, and previous received marketing volumes, etc.&amp;nbsp;&lt;/P&gt;&lt;P&gt;Is there any paper on this where I can read on? or any existing codes?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thanks so much for your help!&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;SAS user&lt;/P&gt;</description>
