svyjdivdec: J-Divergence Decomposition

Description

Estimates the group decomposition of the generalized entropy index

Usage

svyjdivdec(formula, subgroup, design, ...)
# S3 method for survey.design
svyjdivdec(
  formula,
  subgroup,
  design,
  na.rm = FALSE,
  deff = FALSE,
  linearized = FALSE,
  influence = FALSE,
  ...
)
# S3 method for svyrep.design
svyjdivdec(
  formula,
  subgroup,
  design,
  na.rm = FALSE,
  deff = FALSE,
  linearized = FALSE,
  return.replicates = FALSE,
  ...
)
# S3 method for DBIsvydesign
svyjdivdec(formula, subgroup, design, ...)

Value

Object of class "cvydstat", which are vectors with a "var" attribute giving the variance-covariance matrix and a "statistic" attribute giving the name of the statistic.

Arguments

formula

a formula specifying the income variable

subgroup

a formula specifying the group variable

design

a design object of class survey.design or class svyrep.design from the survey library.

...

future expansion

na.rm

Should cases with missing values be dropped? Observations containing missing values in income or group variables will be dropped.

deff

Return the design effect (see survey::svymean)

linearized

Should a matrix of linearized variables be returned

influence

Should a matrix of (weighted) influence functions be returned? (for compatibility with svyby)

return.replicates

Return the replicate estimates?

Details

you must run the convey_prep function on your survey design object immediately after creating it with the svydesign or svrepdesign function.

This measure only allows for strictly positive variables.
