    <description>&lt;P&gt;You used the word ARIMA so I put this in our econometrics board, but maybe this is a more general simulation question.&amp;nbsp;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;

      <description>&lt;DIV class="votecell post-layout--left"&gt;&amp;nbsp;&lt;/DIV&gt;&lt;DIV class="postcell post-layout--right"&gt;&lt;DIV class="post-text"&gt;&lt;P&gt;I am trying to simulate a transfer model in SAS. I am able to simulate the independent x variable using code provided by sas documentation for a&amp;nbsp; &lt;IMG alt="" src="http://support.sas.com/documentation/cdl/en/etsug/63939/HTML/default/images/etsug_arima0367.png" border="0" /&gt;&lt;SPAN&gt;, &lt;/SPAN&gt;&lt;IMG alt="" src="http://support.sas.com/documentation/cdl/en/etsug/63939/HTML/default/images/etsug_arima0368.png" border="0" /&gt;which is an&amp;nbsp;&lt;SPAN&gt;ARIMA(0,1,1)&lt;/SPAN&gt;&lt;/P&gt;&lt;PRE&gt;&lt;CODE&gt;title1 'Simulated IMA(1,1) Series';
data a;
  x1 = 0.9; a1 = 0;
  do i = -50 to 100;
     a = rannor( 32565 );
     x = x1 + a - .8 * a1;
     if i &amp;gt; 0 then output;
     a1 = a;
     x1 = x;
  end;
run;&lt;BR /&gt;&lt;/CODE&gt;&lt;/PRE&gt;&lt;P&gt;but when it comes to simulating the dependent variable y; I start having problems, I have specific values I want for an intercept, numerator, scale and denominator, and including the simulated x variable.i.e&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp; &lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="thes.JPG" style="width: 600px;"&gt;&lt;img src="https://communities.sas.com/t5/image/serverpage/image-id/20428iD9F2B53E6D1F1ED2/image-size/large?v=v2&amp;amp;px=999" role="button" title="thes.JPG" alt="thes.JPG" /&gt;&lt;/span&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Would anyone have any ideas?&lt;/P&gt;&lt;P&gt;Thank You&lt;/P&gt;&lt;/DIV&gt;&lt;/DIV&gt;</description>
