lingini: Linearization of the GINI coefficient I

Description

Estimate the Gini coefficient, which is a measure for inequality, and its linerization.

Usage

lingini(inc, id = NULL, weight = NULL,
          sort = NULL, Dom = NULL, period=NULL,
          dataset = NULL, na.rm = FALSE,
          var_name="lin_gini")

Arguments

inc

Study variable (for example equivalized disposable income). One dimentional object convertable to one-column data.frame or variable name as character, column number or logical vector with only one TRUE value (length of the vector

id

Optional variable for unit ID codes. One dimentional object convertable to one-column data.frame or variable name as character, column number or logical vector with only one TRUE value (length of the vector has to be the same as

weight

Optional weight variable. One dimentional object convertable to one-column data.frame or variable name as character, column number or logical vector with only one TRUE value (length of the vector has to be the same as the column

sort

Optional variable to be used as tie-breaker for sorting. One dimentional object convertable to one-column data.frame or variable name as character, column number or logical vector with only one TRUE value (length of the vector ha

Dom

Optional variables used to define population domains. If supplied, linearization of the GINI is done for each domain. An object convertable to data.frame or variable names as character vector, column numbers or logical vector (length of the v

period

Optional variable for survey period. If supplied, linearization of the GINI is done for each time period. Object convertable to data.frame or variable names as character, column numbers or logical vector (length of the vector has to be the sa

dataset

Optional survey data object convertable to data.frame.

na.rm

A logical value indicating whether missing values in study variable should be removed.

var_name

A character specifying the name of the linearized variable.

Value

• A list with two objects are returned by the function:
• value
  A data.frame containing the estimated GINI coefficients (in percentage) by G. Osier and Eurostat papers.
• lin
  A data.frame containing the linearized variables of the GINI coefficients (in percentage) by G. Osier paper.
