treePostEfficient: Function to efficiently estimate noisy node counts

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

Description

Function to efficiently estimate noisy node counts

Usage

treePostEfficient(release, treeData, n, variance, terminalIndex)

Arguments

release	The truncated differentially private noisy binary tree in vector form
treeData	Data frame with binary tree attributes, including depth and indicators of parent and adjacent nodes. Note that nrow(treeData) == length(release)
n	Number of observations
variance	The variance of the noise used to perturb tree nodes
terminalIndex	Vector of indices corresponding to the terminal leaf nodes of the binary tree
nNodes	Number of nodes in the binary tree, also length(release)

Value

Efficient differentially private binary tree
