Dear Ruth,<br><br>I just read the changelog for RSienaTest rev.93 (04.06.2010), and I saw those messages:<br>"<span dir="ltr" id=":xq">Using composition change with bipartite networks will give an error message – until this is corrected". And "</span><span dir="ltr" id=":xq">Bug fix to treatment of missing data in sparse format bipartite networks".<br>
<br>Since I'm actually using sparse bipartite networks with composition change (RSiena rev.92) I was wondering whether the problem was there before and you fixed it or whether the problem wasn't there before and you signaled it.<br>
Can you please elaborate on that?<br><br>Thanks. Regards,<br>Marco<br></span>
