      <description>Hi everyone,&lt;BR /&gt;
&lt;BR /&gt;
I have SAS 9.2.&lt;BR /&gt;
This is more of a math side question hope someone has an answer.&lt;BR /&gt;
I'm working with acceptance sampling plans specifically double sampling by variables.&lt;BR /&gt;
So I have nonlinear function binomial pdf and which is iterated and calculated according to a array of probabilities [0..1]. &lt;BR /&gt;
I would like to equalize (I mean not exact match, equivalent) the result of my binomial pdf to bivariate normal distribution to find my 3 decision variables which are used to calculate bivariate function. As an example:&lt;BR /&gt;
&lt;BR /&gt;
do p=0.0001 to 0.9999 by 0.0001;&lt;BR /&gt;
Paatt = probbnml(p,n,c);&lt;BR /&gt;
&lt;BR /&gt;
Zp = probit(1-p);&lt;BR /&gt;
&lt;BR /&gt;
Pa1interup=sqrt(n1)*(Zp-k1);&lt;BR /&gt;
&lt;BR /&gt;
Pa2interinup=sqrt(n1)*(Zp-k2);&lt;BR /&gt;
Pa2interindwn=sqrt(n1)*(Zp-k1);&lt;BR /&gt;
Pa2interoutup=sqrt(n1+n2)*(Zp-k3);&lt;BR /&gt;
&lt;BR /&gt;
PA1 = probnorm(sqrt(n1)*(Zp-k1));&lt;BR /&gt;
&lt;BR /&gt;
PAa = probbnrm(sqrt(n1+n2)*(Zp-k3), sqrt(n1)*(Zp-k2), n1/(n1+n2));&lt;BR /&gt;
PAb = probbnrm(sqrt(n1+n2)*(Zp-k3), sqrt(n1)*(Zp-k1), n1/(n1+n2));&lt;BR /&gt;
&lt;BR /&gt;
PA2 = PAa - PAb;&lt;BR /&gt;
&lt;BR /&gt;
PA = PA1 + PA2;&lt;BR /&gt;
end;&lt;BR /&gt;
&lt;BR /&gt;
I would like to make the &lt;I&gt;PA&lt;/I&gt; equivalent to &lt;I&gt;Pattr&lt;/I&gt; by changing &lt;I&gt;k1,k2,k3&lt;/I&gt; for the whole nonlinear function. So its more of a approximation of k values from the result of &lt;I&gt;Pattr&lt;/I&gt; vector. Any information may be helpful.&lt;BR /&gt;
Thanks</description>
