Abstract:
|
When a data cell in a table is suppressed by dropping its value based on a primary cell suppression rule, the value of that cell can still be determined if the table, subtable, or linked tables provide totals, marginal totals, or subtotals. Secondary cell suppression is therefore needed to avoid such disclosures. Two software packages are available to assist researchers with secondary cell suppression: Tau-Argus (Statistics Netherland 2009) and R-statistical package sdcTable (Meindl 2010). But even with this software, there is no simple way to perform secondary suppression for linked tables-that is, tables presenting data on the same cells that share some categories of at least one explanatory variable. Computation may not be trivial and may still require manual reviews, especially when dealing with a large number of linked tables. With an eye toward finding the most straightforward and
