Analyze Data

Public-use Data Analysis System (PDAS)

PDAS is the online analysis tool for SAMHDA studies. This tool allows users to review study variables, run crosstab analyses, perform logistic regressions, and download the results of any analysis to CSV format.


Restricted-use Data Analysis System (RDAS)

Coming soon — a modern, sleek, online analysis tool for SAMHDA studies.

The first version of R-DAS (expected in summer 2017) will allow users to run crosstab analyses (including chi-square tests) and download the results to CSV format for NSDUH data sets. All versions will be Section 508 compliant.
