lcancer: Spatial positions of cases of laryngeal cancer

Description

Description

These data record the spatial positions of cases of laryngeal cancer in the North-West of England between 1974 and 1983, together with the positions of a number of lung cancer patients who were used as controls. The data have been adjusted to preserve anonymity.

The variables are:

Easting a west-east grid reference
Northing a north-south grid reference
Cancer an indicator of laryngeal (1) or lung (2) cancer
