survey (version 4.4-2)

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

Value

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

Arguments

data,x

A svyimputationList object

expr

An expression giving a survey analysis

fun

A function taking a survey design object as its argument
