syn.smooth {synthpop}

syn.smooth

Description

Implements three different smoothing methods for numeric data.

Usage

syn.smooth(ysyn, yobs = NULL, smoothing = "spline", window = 5, ...)

Arguments

ysyn

non-missing synthetic data to be smoothed.

yobs

original data used by all methodds to determine number of decimal places and by method "density" to identify top-coding.

smoothing

a character vector that can take values "spline", "density", or "rmean".

window

width of window for running mean.

...

additional parameters.

Details

Smooths numeric variables by three methods. Default is "spline" that uses a smoothing spline, others are "density" that uses a Gaussian kernel density estimator with bandwidth selected using the Sheather-Jones 'solve-the-equation' method (see bw.SJ) and "rmean" that smooths with a running mean of width "window" (see runningmean).

Value

A vector of smoothed values of ysyn.
