svybmi: Bourguignon (1999) multidimensional inequality indices...

In convey: Income Concentration Analysis with Complex Survey Samples

Description

Estimate indices from the Bourguignon (1999) class, a class of multidimensional inequality measures.

Usage

svybmi(formula, design, ...)

## S3 method for class 'survey.design'
svybmi(
  formula,
  design,
  alpha = 0.5,
  beta = -2,
  dimw = NULL,
  na.rm = FALSE,
  ...
)

## S3 method for class 'svyrep.design'
svybmi(
  formula,
  design,
  alpha = 0.5,
  beta = -2,
  dimw = NULL,
  na.rm = FALSE,
  ...
)

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

Arguments

formula	a formula specifying the variables. Variables can be numeric or ordered factors.
design	a design object of class survey.design or class svyrep.design from the survey library.
...	future expansion
alpha	a scalar defining the exponent of the indicator.
beta	a scalar defining the exponent of the indicator.
dimw	a vector defining the weight of each dimension in the multidimensional deprivation sum.
na.rm	Should cases with missing values 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.

Value

Object of class "cvystat", which are vectors with a "var" attribute giving the variance and a "statistic" attribute giving the name of the statistic.

Note

This function is experimental and is subject to change in later versions.
