Specify the quasi-identifying variables and the number of values they may have here.

For example, gender has 2 values, while age is often encoded with 90 values (e.g. 1-89 and 90+). The number of combinations could be reduced by encoding age in 5 year intervals, with 18 values.

The drop down box for Name provides a number of examples, but you may also enter a custom variable name.
