Format

A 5-by-5 data frame with 5 numeric observations from an experiment on the following 5 groups of beagle dogs.

Details

The canine data set that comes with the cg package is in groupcolumns format for the
prepareCGOneFactorData call. Each column represents a group, and the observations in that group's column are the individual response or outcome values.

The 5 groups are regarded as levels of one factor in the prepareCGOneFactorData, fit, and other methods in the cg package.

An alternative format of this data set is contained in canine.listfmt. See that help file for details, including how it would be read and prepared by cg.

The purpose of this experiment was to evaluate the effect of a physiological dose of estradiol on prostate growth in dogs using ultrasound. See the reference below for details. Comparisons amongst all five groups are of interest.
