Running Sample Code

These requirements apply only to modules with sample code. You must have a software license to run these SAS and/or SUDAAN on your personal computer. If you do not wish to run the code in the tutorial you may view the demonstration of the code instead. Program code used in this tutorial follow procedures available in SAS 9.1, or SAS 8.0 and SUDAAN 9.0 , or SUDAAN 8.0

  • SUDAAN (Version 9 .0; Research Triangle Institute, Research Triangle Park, NC) and/or
  • SAS Version 9.1 (Version 8.02; SAS Institute Inc, Cary, NC) statistical software

The sample code is all SAS or SAS-executable SUDAAN code and the sample datasets provided in this tutorial are SAS datasets for Windows. If you are using a Macintosh or Unix computer, you should download the data files from the NHANES web pages, as these are in SAS transport format (.XPT), and can be extracted and used on Windows, Macintosh or Unix computers.

In Module 10: Save a Dataset, you will also need Microsoft Excel to complete Task 2: Save NHANES data to a Microsoft Excel spreadsheet with SAS. If you do not already have Microsoft Excel, you can read more about it at Microsoft's website.
