KDisclosurePrimary {GaussSuppression}

Construct primary suppressed difference matrix

Description

Function for constructing model matrix columns representing primary suppressed difference cells

Usage

KDisclosurePrimary(
  data,
  x,
  crossTable,
  freqVar,
  mc_hierarchies = NULL,
  coalition = 1,
  upper_bound = Inf,
  ...
)

Arguments

data

a data.frame representing the data set

x

ModelMatrix generated by parent function

crossTable

crossTable generated by parent function

freqVar

name of the frequency variable in data

mc_hierarchies

a hierarchy representing meaningful combinations to be protected. Default value is NULL.

coalition

numeric vector of length one, representing possible size of an attacking coalition. This parameter corresponds to the parameter k in the definition of k-disclosure.

upper_bound

numeric value representing minimum count considered safe. Default set to Inf

...

parameters passed to children functions

Value

dgCMatrix corresponding to primary suppressed cells
