summary.synds: Synthetic data object summaries

In synthpop: Generating Synthetic Versions of Sensitive Microdata for Statistical Disclosure Control

Synthetic data object summaries

Description

Produces summaries of the synthesised variables. When more than one synthetic data set has been generated (object$m > 1), by default summaries are calculated by averaging summary values for all synthetic data copies (see msel argument).

Usage

## S3 method for class 'synds'
summary(object, msel = NULL, maxsum = 7, 
  digits = max(3, getOption("digits")-3), ...)

## S3 method for class 'summary.synds'
print(x, ...)

Arguments

object	an object of class synds; a result of a call to syn.
msel	index or indices of synthetic data copies for which a summary is desired. If NULL (default) summaries are calculated by averaging summary values for all synthetic data copies.
maxsum	integer, indicating how many levels should be shown for factors.
digits	integer, used for number formatting with format.
...	additional arguments passed to summary.
x	an object of class summary.synds.

Details

See summary for more details.

Value

An object of class summary.synds, which is a list with the following components:

m	the number of synthetic versions of the original (observed) data.
msel	index or indices of synthetic data copies for which a summary is produced. If NULL summaries are calculated by averaging summary values for all synthetic data copies.
method	a vector of synthesising methods applied to each variable in the saved synthesised data.
result	a table or a list of tabels (if more than one synthetic data set is selected) with summaries of synthesised variables.
