with.svyimputationList: Analyse multiple imputations

In bschneidr/fastsurvey: Analysis of Complex Survey Samples

Analyse multiple imputations

Description

Performs a survey analysis on each of the designs in a svyimputationList objects and returns a list of results suitable for MIcombine. The analysis may be specified as an expression or as a function.

Usage

## S3 method for class 'svyimputationList'
with(data, expr, fun, ...,multicore=getOption("survey.multicore"))
## S3 method for class 'svyimputationList'
subset(x, subset,...)

Arguments

data, x	A svyimputationList object
expr	An expression giving a survey analysis
fun	A function taking a survey design object as its argument
...	for future expansion
multicore	Use multicore package to distribute imputed data sets over multiple processors?
subset	An logical expression specifying the subset

Value

A list of the results from applying the analysis to each design object.
