Statistical Consulting Service:

• The Statistical Consulting Service at the University of Minnesota provides statistical advice to the researchers in the College of Liberal Arts and sometimes others.

Selected talks

• Slides for an after-dinner talk at the School of Statistics Fortieth Reunion, May 2011. The accomanying text was, alas, never written down.
• An introduction to R, Feb. 10, 2012. Also, how to install R, and the R commands for the five-minute tour. Finally, you can watch an (unedited) video of the presentation from March, 2011.
• Stats Packages and Teaching and other stuff. This is an old talk, but seems to have some relevance today; similar sentiments are expressed at this site, but I think more elegantly in this talk.
