Disclosure Risk Continuous Scaled Variables
The (distance-based) disclosure risk for continous key variables is between 0.000% and 100.000% in the modified data.
In the original data, the risk is assumed to be approximately 100.000%.
Hierarchical risk
- modified data: 0.115 (0.011%)
- original data: 0.149 (0.014%)
