note pub9trunc: Earlier analyses (pubreg04a.do 2006-09-20) showed  ///
that cases with a large number of articles were outliers. Program  ///
pubreg04b.do 2006-09-21 examined different transformations of pub9 ///
and found that truncation at 20 was most effective at removing     ///
the outliers. \ jsl 2008-04-09.
