A method for managing re-identification risk from small geographic areas in Canada

Table 5 Comparison of unbalanced data modeling methods.

Model Evaluation for the 5% Uniqueness Threshold
	AUC	Sensitivity	Specificity
Down-Sampling	0.9849	0.87	0.996
KZ	0.9849	0.449	0.992
Model Evaluation for the 20% Uniqueness Threshold
	AUC**	Sensitivity	Specificity
Down-Sampling	0.947	0.74	0.98
KZ	0.949	0.59	0.949

**We tested the difference between the AUC values, and the difference was statistically significant between the two methods only for 20% uniqueness at an alpha level of 0.05
