determineMechanism: Determine Mechanism

In privacytoolsproject/PSI-Library: Differentially Private Statistical Releases for Privacy Preservation

Description

This is a set of helper functions to determine which mechanism to use when calculating the histogram (either the stability mechanism or the Laplace mechanism).

Usage

determineMechanism(varType, rng, bins, nBins, granularity)

Arguments

varType	Character, the variable type.
rng	Numeric, a priori estimate of the lower and upper bounds of a variable taking numeric values. Ignored for categorical types. Maybe be null for numeric or integer types, in which case the stability mechanism is used.
bins	Character or numeric, the available bins or levels of a variable. Character for categorical variables, a vector of numbers for numeric variables.
nBins	Integer, the number of bins to release.
granularity	Numeric, the width of each histogram bin.

Value

a string indicating the mechanism to use when constructing the differentially private histogram
