Help for Students in PA552, Analytic Methods 2

Also, look for other possible helpful links and files on my web site. Look especially in the Data folder for data files (and associated documentation files) for use on course projects and computer exercises, and look on the "Resources for Students" page at the links under "Data, Statistics, Statistical Computing". Finally, join the PA552 listserv.
