An experiment was conducted to study the <em>O2UP</em>, oxygen uptake in milligrams of oxygen per minute, given five chemical measurements: biological oxygen demand (BOD), total Kjeldah nitrogen (TKN), total solids (TS), total vital solids (TVS), which is a component of TS, and chemical oxygen demand (COD), each measured in milligrams per liter (Moore, 1975).

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.
