<DIV>Dear RSiena Users,<BR></DIV>
<DIV>I am trying to include an average exposure effect in a diffusion model of a dichotomous behavior variable binge.</DIV>
<DIV> </DIV>
<DIV>What is the syntax for adding the effect?</DIV>
<DIV> </DIV>
<DIV>This is what I have tried:</DIV>
<DIV> </DIV>
<DIV>myeff[myeff$effectName=='average exposure effect on rate binge' & myeff$type=='rate', 'include'] <- TRUE</DIV>
<DIV> </DIV>
<DIV>Thanks!</DIV>
