syn.sample

Synthesis by simple random sampling

Description

Generates a random sample from the observed data.

Usage

syn.sample(y, xp, smoothing = "", cont.na = NA, proper = FALSE, ...)

Arguments

`y`	an original data vector of length `n`.
`xp`	a target length `k` of a synthetic data vector.
`smoothing`	smoothing method for a continous variable.
`cont.na`	a vector of codes for missing values for continuous variables that should be excluded from smoothing.
`proper`	if `proper = TRUE` values are sampled from a bootstrapped sample of the original data.
`...`	additional parameters passed to `sample`.

Details

A simple random sample with replacement is taken from the observed values in y and used as synthetic values. A Guassian kernel smoothing can be applied to continuous variables by setting smoothing parameter to "density". It is recommended as a tool to decrease the disclosure risk.

Value

A list with two components:

`res`	a vector of length `k` with synthetic values of `y`.
`fit`	a name of the method used for synthesis (`"sample"`).
