Synthesis by linear regression

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.
