Description
This data concerns mean weights of the brains and bodies of 62 species of mammals.
The first column contains values of species (Species), the second column is brain
weight in grams (Brain), and the third column is body weight in kilograms (Body).
Usage
1
Format
A data frame with 62 observations on the following 3 variables.
Speciesa string vector for species names
Braina numeric vector
Bodya numeric vector
Details
The goal is to investigate the linear relationship between the natural logarithm of brain weight
and that of body weight, assuming that brain weights
are observations from gamma distributions and their means depend on
logarithms of body weights.
