| 12/27/06: | Welcome to the class
website! Please see the syllabus for details on the course, but here is a
quick overview: Stat 423 is a 4-credit first course on multiple regression,
aimed at
mathematically trained undergraduates.
Prerequisites for the course are:
Stat 342, Stat/Math 390, Stat 421, or Stat/Econ 481. Math 308 is
recommended. For a slightly higher level class, please see Stat 504.
We will use "Applied
Regression Analysis, Linear Models, and Related Methods", by John Fox
(1997)
as the main text for the course.
The main goals for the class are:
- That you learn to run a multiple regression analysis, using
the statistical software R,
and to interpret the results correctly.
- That you learn to interpret and critique regression analyses
done by others.
