Secure SDA

Secure Survey Documentation and Analysis (SSDA) is an online data analysis program that performs bi-variate cross-tabulation, comparison of means, correlation, and regression analyses. SSDA is designed to provide a safe, reliable way to distribute restricted-use data publicly, thereby, democratizing access to data previously unavailable or that required special procedures to obtain. SSDA automates several disclosure protections that prevent the use of organization-defined high-risk variables, singularly or in combination, as well as output (e.g. unweighted N's). When the organization-defined rules are violated by an attempted analysis, the resulting output is completed suppressed or partially suppressed.

Restricted-use RCMD studies that with SSDA capabilities will be listed as they become available.
