<p><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Hi folks</span>
<o:p></o:p></p>
<p><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I've recently installed admb 10.1 on a 'real' system (SuSE Linux Enterprise Server 11 SP1, gcc 4.3) and I've noticed different behaviour vs my 32-bit admb 10.0 windoze setup. Specifically the
ic > imax is minimum attained issue pops up on the 10.1 where it does not on the 10.0. Both installations give me the same parameter estimates, but obviously a) something is different, b) it appears to be worse in the newer version and c) it would be nice
to know why. The first thing that came to mind is that the default value of the convergence criterion might have changed between 10.0 and 10.1 but I ran the new system with -crit 1e-4 and same behaviour.
</span><o:p></o:p></p>
<p><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Any ideas? </span>
<o:p></o:p></p>
