Stat 206: Multivariate Analysis
Multivariate analysis is about handling vector valued
data. In ordinary regression modeling we are used to
a vector valued predictor. But a vector valued response
variable brings new issues.
Sometimes we can handle a k dimensional response by
treating it as k unrelated 1 dimensional problems.
But often that approach will fail to find the key
structure. Sometimes we are forced to study the
data as an inherently k dimensional thing. It can also
pay to reduce the dimension k, sometimes to 3 or 2 where
plotting is available, sometimes to k=1 where ordinary
methods can then be applied. Also, some of the methods are useful
for exploratory work and not just for modelling responses.
This course looks at multivariate methods. The outlook
is applied. There will be a midterm and problem sets.
Students are expected to use R to do the problem sets.

The main text is "Multivariate Statistical Methods: a Primer"
by B.F.J. Manly.
The supplementary text is "Modern Applied Statistics with S"
by Venables and Ripley. That book explains how to use R.
If you already know how to use R you don't need to buy it.

Be sure to give Axess a working email address:
- Homework: 4 to 6 problem sets   (70%)
- Midterm: Wednesday February 22 in class   (30%)
I expect to send a small number of important emails about
problem sets and the homework there.
Most other announcements will be made in class.
Late penalties apply:
We will count days late on each problem set.
Each day late is penalized by 10% of the homework value.
Homework more than 3 days late will ordinarily get 0.
If you're travelling, you can email a pdf file.
For sickness, interviews and other events,
up to 3 late days total are forgiven at the end of
the quarter. (Work late enough to get zero does not
get redeemed though.)
