Statistical disclosure in three-dimensional tables: general tables 

W.A. Luijten
Statistical Disclosure in Three-Dimensional Tables: General Tables Statistical offices, as for instance the U.S. Census Bureau, are concerned with problems of protecting confidential information when publishing data in statistical tables. One method to avoid disclosure is the method of cell suppression, in which the values of the sensitive cells in the table are suppressed from publication. To prevent the values of the sensitive cells from being calculated from the tables totals, additional suppressions are necessary. The problem of minimizing the loss of information caused by the additional suppressions is a difficult optimization problem. Some heuristics for cell suppresion for general three-dimensional tables are presented and compared in the thesis.
