PEGS Data Freezes
The PEGS data are stored securely in a single centralized, shared repository to ensure consistent, reproducible, and comparable analyses. PEGS comprises a compatible, multi-dimensional collection of datasets in consistent and programmatically extractable formats, as shown in the figure on the right, and Data Components below. PEGS data are updated on a quarterly basis with additional participants, new variables, participant updates, and any additional data components. We are continually building analysis pipelines and workflows to enable efficient, reproducible, insightful, and collaborative research using the PEGS data.
