Disclosure Risk Continuous Scaled Variables

The (distance-based) disclosure risk for continous key variables is between 0.000% and 95.431% in the modified data.

In the original data, the risk is assumed to be approximately 100.000%.

Hierarchical risk

  • modified data: 11.898 (0.046%)
  • original data: 11.898 (0.046%)
