synthetic: Create fully synthetic longitudinal dataset.

In SOCR/DataSifterII: Data Sifter II Algorithm to Create Privacy-preserving Time-varying Data

Description

When data privacy is the major issue of time-varing data sharing, we consider this fully synthetic version of DataSifter II. It obfuscate longitudinal data by generating random numbers within the neighborhood of a longitudinal variable at a given visit time. Thus, the within-subject covariance structure might be changed by this process.

Usage

synthetic(data, lnames, timevar, ID, N)

Arguments

data	A data frame in long format.
lnames	A vector of longitudinal variables names.
timevar	The time variable or cluster varaible name.
ID	Name of the ID variable in the dataset.
N	The number of closest records to be considered as neighborhood.

Value

Fully synthetic Sifted data.
