Applied Regression Including Computing and Graphics Workshop

The late John Tukey in his book Exploratory Data Analysis stated “Exploratory data analysis is detective work – numerical detective work — or counting detective work — or graphical detective work”. The approach of Dennis Cook and Sanford Weisberg is to use graphical methods, including E.D.A techniques, to study how response variables depend on predictors – inferential detective work. This workshop demonstrated how dynamic graphical methods and inferential statistics can be taught together to form a new view of regression. This article reports a workshop by Professor Sanford Weisberg — Applied Regression Including Computing and Graphics (ARICG) –run by the LTSN Maths, Stats & OR Network that was held on the 3 May 2001 at the Department of Statistics, Glasgow University. The workshop aimed to give an insight into the graphical and regression techniques that are described in the textbook: Applied Regression Including Computing and Graphics by R. Dennis Cook and Sanford Weisberg (Wiley) – denoted ARICG in this article. This event introduced material from the book (unfortunately in short supply in the UK at the time), and introduced the free software Arc.
