In GaussSuppression: Tabular Data Suppression using Gaussian Elimination

Method for finding dominant cells according to (possibly multiple) n,k dominance rules.

Description

Supports functionality for grouping contributions according to holding variables, as well as calculating dominance in surveys with a given sampling weight. Two methods are implemented, depending on whether the sampling weights sum to total population. The parameter tauArgusDominance determines this. If FALSE, unweighted contributions are compared to weighted cell values. If TRUE, the method described in in the book "Statistical Disclosure Control" (Hundepool et al 2012, p. 151) is used.

Usage

FindDominantCells(
  x,
  inputnum,
  num,
  n,
  k,
  charVar_groups,
  samplingWeight,
  tauArgusDominance = FALSE,
  returnContrib = FALSE,
  maxContribution = NULL
)

Arguments

x	model matrix describing relationship between input and published cells
inputnum	vector of numeric contributions for each of the input records
num	vector of numeric values for each of the published cells
n	vector of integers describing n parameters in n,k rules. Must be same length as k parameter.
k	vector of numeric values describing k parameters in n,k rules, where percentages are described as numbers less than 100. Must be same length as n parameter.
charVar_groups	vector describing which input records should be grouped
samplingWeight	vector of sampling weights associated to input records
tauArgusDominance	logical value, default FALSE. determines how to handle sampling weights in the dominance rule (see details).
returnContrib	logical value, default FALSE. If TRUE return value is the percentage of the first n contributors
maxContribution	Possible precalculated output from MaxContribution as input. To speed up.

Value

logical vector describing which publish-cells need to be suppressed.
