Statnotes collection from NCSU

For a nice applied collection of notes for multivariate analysis, see G. David Garvin's Statnotes. These notes are part of a graduate course, "Quantitative Research in Public Administration" at North Carolina State University (NCSU). Many of the entries include a FAQ section, as well as links to software and a list of references. All this on top of clear explanation of the principles for each topic.
