Generalized entropy index Decomposition

Description

Estimates the group decomposition of the generalized entropy index

Usage

svygeidec(formula, subgroup, design, ...)

## S3 method for class 'survey.design'
svygeidec(formula, subgroup, design, epsilon = 1, na.rm = FALSE, ...)

## S3 method for class 'svyrep.design'
svygeidec(formula, subgroup, design, epsilon = 1, na.rm = FALSE, ...)

## S3 method for class 'DBIsvydesign'
svygeidec(formula, subgroup, design, ...)

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
epsilon	a parameter that determines the sensivity towards inequality in the top of the distribution. Defaults to epsilon = 1.
na.rm	Should cases with missing values be dropped? Observations containing missing values in income or group variables will be dropped.

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.

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.
