Esophageal cancer data modified slightly to create a balanced three-way factorial design

Description

Breslow and Day (1980) studied the effect of age, tobacco, and alcohol on esophageal cancer rates at Ile-et-Vilaine, France. Data are altered slightly to make the design balanced, and to allow enough degrees of freedom to perform a fully factorial three way ANOVA.

Usage

Format

The dataset contains four variables:

age grp.
