syn.norm

Synthesis by linear regression

Description

Generates univariate synthetic data using linear regression analysis.

Usage

syn.norm(y, x, xp, proper = FALSE, ...)

Arguments

`y`	an original data vector of length `n`.
`x`	a matrix (`n` x `p`) of original covariates.
`xp`	a matrix (`k` x `p`) of synthesised covariates.
`proper`	a logical value specifying whether proper synthesis should be conducted. See details.
`...`	additional parameters.

Details

Generates synthetic values using the spread around the fitted linear regression line of y given x. For proper synthesis first the regression coefficients are drawn from normal distribution with mean and variance from the fitted model.

Value

A list with two components:

`res`	a vector of length `k` with synthetic values of `y`.
`fit`	a data frame with regression coefficients and error estimates.
