pollution

Data on the relation between weather, socioeconomic, and air pollution variables
and mortality rates in 60 Standard Metropolitan Statistical Areas (SMSAs) of the
USA, for the years 1959-1961. Some of the variables are highly collinear.

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),
