Overview
We will cover simple and multiple
regression, one and two-way
analysis of variance and analysis
of covariance. The emphasis will
be placed on selected practical
tools using SAS rather than on the
mathematical manipulations. Want
to understand the theory so that
we can apply it appropriately.
