springs

Failure times of 60 springs divided into 6 groups of 10, with each group
 subject to a different level of stress. Some of the times are right-censored.

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),
