Replications in synthetic data

Description

Determines which unique units in the synthesised data set(s) replicates unique units in the original observed data set.

Usage

replicated.uniques(object, data, exclude = NULL)

Arguments

object	an object of class synds, which stands for 'synthesised data set'. It is typically created by function syn() and it includes object$m synthesised data set(s).
data	the original observed data set.
exclude	a single string or a vector of strings with name(s) of variable(s) to be excluded from the identification of uniques.

Value

A list with the following components:

replications	a vector (for object$m = 1) or a data frame with object$m columns (for object$m > 1) with logical values indicateing duplicates in mth synthetic data set.
no.replications	a single number or a vector of object$m integers indicating the number of duplicates in the synthetic data set(s).
no.uniques	a number of unique individuals in the original data set.
per.replications	a single number or a vector of object$m numeric values indicating the percentage of duplicates in the synthetic data set(s).
