MaskJointDensity-package Masking, unmasking and restoring confidential data.
actualPosition Getting a Sample from Marginal Density Functions
anyNA Checks for NA in a vector
barredToActual Purely used in actualPosition
calc_muX Calculate the moments
CheckRho An old artefact from testing, purely for backwards compatibility
createNoise Create a noise
density_Rmask Density function
Dg Purely used in rho_0
encriptNoise encript noise
EQsampleDensity Samples from a bunch of nodes on a grid.
findOrder_Rmask order determination
FPI2002Data A real life dataset consisting of the bilateral investment between many different countries in 2002, as well as the corresponding covariates from 2001. This was to eliminate any dual causality element in data analysis.
fY_Rmask density of Y
generalizedJointF Purely used in getSampleFromMarginalDistributionOfUnmaskedData
getSampleBasedOnUnmaskedData Second core function the End-User uses to obtain the samples from the marginal distributions of the unmasked data
getSampleFromMarginalDistributionOfUnmaskedData Second function the End-User uses to obtain the samples from the marginal distributions of the unmasked data
GH_Quadrature The seven weights used for Gaussian Hermite Quadrature
gRho Purely used in rho_0
G_Point7 The seven points used for Gaussian Hermite Quadrature
lambda_Rmask expectation of Legendre polynomial
mask Core function the Data Provider uses to mask the confidential original data to give to the user
maskBatch A batch function that the Data Provider can use to mask the confidential original data to give to the user, all in one batch
MaskJointDensity Masking, unmasking and restoring confidential data.
moments moment
positions Function for finding the positions of the node representing the points at which to sample from the kernel density estimate.
P_Rmask Legendre polynomial
qkdeSorted A slightly altered version of qkde from package ks
rho_0 Purely used in generalizedJointF
rmulti Simple way to generate noise
sampleDensity A function used to simulate a sample from a kernel function, where the kernel function is determined by a given sample.
unmask First core function used by End-User
unmaskAndGetSampleBatch Batch function that allows the user to unmask a number of variables as well as to sample from the estimated joint density function. Serves as a wrapper for the first and second functions the End-User calls to obtain the samples from the marginal distributions of the unmasked data.
