 Description of the Course:       The goal of this course is to continue further study of regression analysis. Topics to be covered include: Simple/Multiple Linear Regression Models (with emphasis on model diagnostics, model selection etc.), ANOVA (including multiple comparisons, ANCOVA), plus an introduction to repeated measure analysis, logistic regression, and poisson regression if time allows.

Statistical Computing:  R, a free version of S/S+, is the primary statistical computing package for this class. It can be downloaded from the website of CRAN. The following webpage contains excellent help information of R, including several useful manuals, and FAQ about R: http://stat.ethz.ch/R-alpha/.  Also, you will need the Acrobat Reader  in order to view pdf files.
