quantileDataAccess: Differentially Private Quantile Data Access Function
Description
This function performs the data access step in the computation of a
differentially private quantile. The utility vector is computed as in
Smith2011a;textualDPpack, while the sensitivities are
calculated based on bounded and unbounded differential privacy
Kifer2011DPpack according to the theoretical values
Gillenwater2021DPpack.
List of a vector corresponding to the utility function, the sorted
and clipped vector of inputs and the sensitivity calculated based on
theoretical values.
Arguments
x
Numeric vector.
quant
Real number between 0 and 1 indicating which quantile to return.
lower.bound
Real number giving the lower bound of the input data.
upper.bound
Real number giving the upper bound of the input data.
