bike

The times taken to cycle up a hill, as function of the bicycle
seat height, use of dynamo, and tyre pressure. 16 runs were made
using a factorial design.

datasets

Contains the datasets and a few functions for use with
the practicals outlined in Appendix A of the book
Statistical Models (Davison, 2003, Cambridge University Press),
