Teaching

Managing Research Data for the Social Sciences

This 2 to 3 credit hour graduate level course, taught in the summer, is designed to teach the skills necessary to read, reorganize, transform, clean, archive, and export simple or complex data. The primary tool used in the class is the SAS system. Structured Query Language (SQL) in both SAS and Microsoft Access receives a strong emphasis. The course emphasizes structured documentation of data, with the Data Documentation Initiative standard (DDI) being the prime example.

SAS Enterprise Guide: Point and Click with SAS

This hands-on workshop is an introduction to Enterprise Guide, a Microsoft Windows program from SAS Institute that makes much of the functionality of the SAS system accessible through a graphical user interface. Offered through the KU Information Services Workshops.

Text Mining with SAS

This hands-on workshop is an introduction to SAS Enterprise Miner and Text Miner, offered peroidically and by request.
