KDisclosurePrimary

Function for constructing model matrix columns representing primary suppressed
difference cells

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 suppression of disclosive cells is also included. 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>.
