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.
Value
k with synthetic values of y.
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.
