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 (2005),
"Applied Linear Regression," 3rd edition, Wiley. It includes all the
data sets discussed in the book (except one), and a few functions that
are tailored to the methods discussed in the book.  As of version 2.0.0,
this package depends on the car package. Many functions formerly
in alr3 have been renamed and now reside in car.
Data files have beeen lightly modified to make some data columns row labels.
