Part of the Yale Institution for Social and Policy Studies (ISPS) Dataverse, the ISPS Data Archive includes “replication packages” (i.e., data, analysis code, requisite documentation, and other associated materials) for research supported by ISPS. Replication packages have been reviewed to enable long-term usability using the YARD tool. Read about our approach to curating for reproducibility.
