Instructions to apply online for CVFS restricted-use data via the Virtual Data Enclave (VDE) Method
This method allows a user to access CVFS restricted-use data files via a remote desktop connection to a virtual machine operating on ICPSR’s server. Data files cannot be downloaded to the user’s own computer. The user analyzes the files using the software available on the virtual machine. Select this method if you need access to software tools to analyze the data. (Available software includes SPSS, SAS, Stata, StatTransfer, SUDAAN (SAS-callable), R, HLM, and MPlus.) Or, select this method if you do not have a stand-alone desktop computer that meets the requirements for access via Method 1 – Secure Dissemination.
