withPV.survey.design {survey}

Analyse plausible values in surveys

Description

Repeats an analysis for each of a set of 'plausible values' in a survey data set, returning a list suitable for mitools::MIcombine. The default method works for both standard and replicate-weight designs but not for two-phase designs.

Usage

## S3 method for class 'survey.design'
withPV(mapping, data, action, rewrite=TRUE, ...)

Arguments

mapping

A formula or list of formulas describing each variable in the analysis that has plausible values. The left-hand side of the formula is the name to use in the analysis; the right-hand side gives the names in the dataset.

data

A survey design object, as created by svydesign or svrepdesign

action

With rewrite=TRUE, a function taking a survey design object as its only argument, or a quoted expression. With rewrite=TRUE a function taking a survey design object as its only argument, or a quoted expression with .DESIGN referring to the survey design object to be used.

rewrite

Rewrite action before evaluating it (versus constructing new data sets)

...

For methods

Value

A list of the results returned by each evaluation of action, with the call as an attribute.
