pooledVarDataAccess: Differentially Private Pooled Variance Data Access Function

Description

This function performs the data access step in the computation of a differentially private pooled variance. The true values are computed using the theoretical formula and var, while the sensitivities are calculated based on bounded and unbounded differential privacy Kifer2011DPpack according to the theoretical values Liu2019bDPpack.

Usage

pooledVarDataAccess(samples, lower.bound, upper.bound, approx.n.max)

Value

List of the true pooled variance and the sensitivities calculated based on bounded and unbounded differential privacy.

Arguments

samples

List of vectors from which to compute the pooled variance.

lower.bound

Real number giving the lower bound of the input data.

upper.bound

Real number giving the upper bound of the input data.

approx.n.max

Logical indicating whether to approximate n.max, which is defined to be the length of the largest input vector. Approximation is best if n.max is very large.
