<p class="MsoNormal">Dear ADMB users,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I would like to fit a model using ADMB-RE for which I require the det() and inv() matrix functions, which do not seem to be implemented for the random effects module. Reading through previous messages in the mailing list archive, it seems
that there may be a work-around for this problem:<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">At present, my knowledge of C++ is rather limited and I am not sure how to proceed in attempting this. Would anyone be happy to provide further guidance?<o:p></o:p></p>
