Review Material

Before entering the Fall 2007 section of STAT 704, you should have a knowledge of certain basic statistical methods, such as: descriptive statistics, basic graphs and plots, elementary probability, discrete and continuous random variables, sampling distributions, point and interval estimation, and hypothesis testing. If you have had a course in elementary statistics (not "mathematical statistics"), you have probably covered this material. If you need a review of it, you may wish to familiarize yourself with any of the following material:

Textbook:
Required Textbook: "Applied Linear Statistical Models" (5th edition) by Kutner, Nachtsheim, Neter, and Li.
(It is rather expensive, but it is a very nice book and it will also be the book used for STAT 705 in the spring.)

Supplementary Books (NOT required):
"Linear Models with R" by Faraway, J.J.
"Extending the Linear Model with R" by Faraway, J.J.
"An R and S-plus Companion to Applied Regression" by Fox, J.
"Statistical Analysis and Data Display" by Heiberger and Holland.
"Statistical Research Methods in the Life Sciences" by Rao, P.V.

Available Computing Resources: R is available as a free download from the CRAN home page) and students who want SAS can buy a copy from USC Computer Services.
These packages are also available on the computers in the labs in LeConte College (and a few other buildings). Help in using R can be found on the CRAN home page.
