replicated.uniques

Replications in synthetic data

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

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

`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.

A list with the following components:

`replications`	a vector (for `object$m = 1`) or a data frame with `object$m` columns (for `object$m > 1`) with logical values indicateing duplicates in `m`th synthetic data set.
`no.replications`	a single number or a vector of `object$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).
