NOTE: These are
the Fall 2004 course notes for the first semester of my graduate statistics
courses. The notes for the second semester course,
Sociology 63993, are also available.
These pages make extensive use of Stata and SPSS. If you are mostly interested
in learning how to use Stata, the
Stata Highlights page lists several of the
most relevant handouts from both courses. Some pages are more "stand
alone" than others, so adjacent handouts may help clear up any questions you
have.
Feel free to

if you have comments or suggestions.
NOTE: The following special types of files are used on this web page.
Pdf files. Require Adobe Acrobat.
SPSSWIN files.
