p5.12

The <code>p5.12</code> data frame has 27 observations on 3 variables, with
responses replicated 3 times. Averages and standard deviations are calculated
for each level of the experimental design.

datasets

Most of this package consists of data sets from the
textbook Introduction
to Linear Regression Analysis, by Montgomery, Peck
and Vining.  All data sets from the 3rd edition are included
and many from the 6th edition are also included.
The package also contains some additional data sets and functions.
