Online Analysis Using SDA

The online analysis system allows you to run both simple and complex analyses, recode and compute new variables, and subset variables or cases for downloading. The software powering the system, named Survey Documentation and Analysis (SDA), was developed by the Computer-assisted Survey Methods Program (CSM) at the University of California, Berkeley.

Weight

Please note that weights may affect analysis results.

The NSAF employs a complex sample design, thus appropriate weights are essential to produce state and national estimates that are representative of the population. Five categories of weights are currently available with the NSAF data, each appropriate for a different set of respondents or group of questions from the survey. The five weight categories are: focal child, adult pair, random adult, childless adult, and family. Within each category, there are separate weights for producing state- and national-level estimates. Detailed information about the weights may be found at the Urban Institute Web site.

If you're having trouble with SDA utilities, you may wish to consult the online help files for SDA users provided by the Computer-assisted Survey Methods Program (CSM) at the University of California, Berkeley.
