Are Splines fulled implemented in both ADMB and ADMB-RE? I struct some problems with them in ADMB-RE, but haven't had time to look closer as yet....<br>

Hi Mark,<br>
<br>
I found <a href="http://en.wikipedia.org/wiki/Spline_interpolation" target="_blank">http://en.wikipedia.org/wiki/Spline_interpolation</a> to be informative.<br>
<br>
<br>
Also, inspired by your email, I've discovered that there's very useful<br>

<br>
</div>I just added that 2nd link to the FAQ item about splines, but obviously<br>
that's no substitute for some proper documentation in the user manual.<br>

Or a simple description of how cubic splines are implemented in general.<br>

There are some examples on how to use them in ADMB<br>

admb 10.0 and 9.1 on linux give me the same behaviour. so not a version<br>
thing. one day "soon" i'll find time to debug..<br>
<br>
<br>
<br>
convergence critieria is not necessarily the issue because that determines<br>
ultimate convergence, not the question of whether the process has hung<br>
<br>
<br>

debugging i'm not much wiser!<br>

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