Central manuals and guidelines

You can find a detailed explanation of the procedure of remote data access, including the descriptions of the "Internal Use Mode" and the "Presentation / Publication Mode", the functionalities of JoSuA as well as help for troubleshooting in the “Manuals for Remote Data Access and On-Site Use at the FDZ of the BA at the IAB" (pdf). Please read these manuals before using JoSuA.

In addition to this document, it is mandatory to adhere to the "Guidelines for the Design of Evaluation Programmes and Analysis Results" (pdf). This is the key document that shows you how to write the programme files and how to generate results that comply with data protection regulations. Please also always use the Stata templates (zip) for evaluation programmes provided by the FDZ, in which the guidelines are implemented as examples.
