Data collected in an experiment in which rats were injected with a dose of a
drug approximately proportional to body weight.  At the end of the experiment,
the animal's liver was weighed, and the fraction of the drug recoved in the
liver was recorded.  The experimenter expected the response to be independent
of the predictors.


datasets

This package is a companion to the textbook S. Weisberg (2014),
"Applied Linear Regression," 4rd edition, Wiley. It includes all the
data sets discussed in the book and one function to access the textbook's
website.
This package depends on the car package.  Many data files in this package
are included in the alr3 package as well, so only one of them should be
loaded.
