Both instructors are professors of applied statistics at the University of Minnesota. Much of their research over the last two decades, and much of their teaching, has been in the areas of regression and graphics. They have jointly written over 25 works, including the textbook An Introduction to Regression Graphics that is the basis of this course and the 1982 monograph Residuals and Influence in Regression. They are both fellows of the ASA.
