Effects on Analysis Arising from Confidentialising Data Using Random Rounding

Government statistical agencies collect data on individuals. These data can have personal information that will lead to individual identification. The information gathered is often released and used by other agencies. In order to preserve confidentiality (people’s privacy) the data are treated in a...
