Sociology Graduate Statistics I

Richard Williams, Instructor

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 email Richard Williams if you have comments or suggestions.
