ICPSR offers online analysis components for selected data collections using Survey Documentation Analysis (SDA). This allows users to explore datasets using certain statistical procedures without downloading data and setup files. Click on the Online Analysis link that appears on the Study page. If you do not see an Online Analysis link, the study is not available for online analysis.
