Abstract:
|
Multiple variations of "conventional" data rounding procedures have been proposed and are practiced to protect sensitive tabular cells. Irrespective of the inherent procedural variations, all these procedures fall under a general category of "indiscriminant" rounding. The "indiscriminant" rounding procedure results in reduced data utility and quality. To improve the overall utility and quality of the published tabular data, we instead propose using a selective rounding procedure for tabular cells. The proposed procedure could be implemented by using multiple different techniques/tools currently available to the statistical agencies.
