%description
A statistical disclosure control tool to protect tables by suppression
using the Gaussian elimination secondary suppression algorithm (Langsrud,
2024) <doi:10.1007/978-3-031-69651-0_6>. A suggestion is to start by
working with functions SuppressSmallCounts() and SuppressDominantCells().
These functions use primary suppression functions for the minimum
frequency rule and the dominance rule, respectively. Novel functionality
for targeted attribute disclosure protection is also included. See
Langsrud (2026) <doi:10.1007/978-3-032-37883-5_8> and references therein.
General primary suppression functions can be supplied as input to the
general working horse function, GaussSuppressionFromData(). Suppressed
frequencies can be replaced by synthetic decimal numbers as described in
Langsrud (2019) <doi:10.1007/s11222-018-9848-9>. This approach can also be
used as a flexible tool for suppression of post-published tabular data
(Langsrud and Bøvelstad, 2022) <doi:10.1007/978-3-031-13945-1_8>.
