disclosure_risk {sdcSpatial}

Calculate disclosure risk for raster cells

Description

The disclosure risk function is used by is_sensitive() to determine the risk of a raster cell. It returns a score between 0 and 1 for cells that have a finite value (otherwise NA).

Usage

disclosure_risk(x, risk_type = x$risk_type)

Arguments

x

sdc_raster object.

risk_type

character: "external", "internal", "discrete".

Details

Different risk functions include:

• external (numeric variable), calculates how much the largest value comprises the total sum within a cell

• internal (numeric variable), calculates how much the largest value comprises the sum without the second largest value

• discrete (logical variable), calculates the fraction of TRUE vs FALSE

Value

raster::raster object with the disclosure risk.
