Also, Amelia doesn&#39;t always produce that odd result, but it tends to do it more frequently for some variables than it does for others.  I&#39;m happy to provide data, scripts, etc. <div><br><br><div class="gmail_quote">

Hi Folks, <div><br>I&#39;m getting some odd levels in my post-imputation data: <br><br></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px">&gt; levels(as.factor(a.out$imputations[[1]]$facts_convict))<br>

</div><div>Not sure how/why the double &quot;1&quot; crept in during imputation.  As you can imagine, ologits end up being odd, with two estimates for &quot;1&quot;.  Any thoughts? </div><div><br>Don<br><br></div><div>Donald Braman<br>
