<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Dear Ruth,<br>
<br>
for the first time I've tried modelling some networks (83 x 577 nodes) with low
Jaccard coefficient (around 0.8 - 1) and the estimation stops during phase 2
subphase 1 giving me this error message:<br>
<br>
Error in x$FRAN(zsmall, xsmall) : Unlikely to terminate this epoch:<br>
<br>
Is this likely to be correlated to the fact that there is a low Jaccard?
Otherwise, what is it due to?<br>
<br>
I'm using RSiena rev 83 <span id=":u7">on my machine (Linux
2.6.31-21-generic #59-Ubuntu SMP x86_64) using the patch you mentioned in
the previous thread.</span><br>
<br>
Thanks a lot.<br>
Best,<br>
<br>
Marco<o:p></o:p></span></font></p>
