lingini2: Linearization of the GINI coefficient II

Description

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

Usage

lingini2(inc, id = NULL, weight = NULL, sort = NULL, Dom = NULL,
          period=NULL, dataset = NULL, na.rm = FALSE, var_name="lin_gini2")

Arguments

inc

either a numeric vector, 1 column data.frame, matrix, data.table giving the equivalized disposable income, or (if dataset is not NULL) a character string, an integer or a logical vector (length is the same as 'dataset

id

optional; either 1 column data.frame, matrix, data.table with column names giving the personal IDs, or (if dataset is not NULL) a character string, an integer or a logical vector (length is the same as 'dataset' colum

weight

optional; either a numeric vector, 1 column data.frame, matrix, data.table giving the personal sample weights, or (if dataset is not NULL) a character string, an integer or a logical vector (length is the same as 'dat

sort

optional; either a numeric vector, 1 column data.frame, matrix, data.table giving the personal IDs to be used as tie-breakers for sorting, or (if dataset is not NULL) a character string, an integer or a logical vector

Dom

optional; either a data.frame, matrix, data.table with column names giving different domains, or (if dataset is not NULL) character strings, integers or a logical vectors (length is the same as 'dataset' column count)

period

optional; either a data.frame, matrix, data.table with column names giving different periods, or (if dataset is not NULL) character strings, integers or a logical vectors (length is the same as 'dataset' column coun

dataset

an optional; name of the individual dataset data.frame.

na.rm

a logical indicating whether missing values should be removed.

var_name

a character string specifying the name of the linearized variable.

Value

• The function returns two values:
• value
  a data.frame containing the estimate(s) the gini coeffients (in percentage) by domain, or (if Dom is NULL) totals, using Tille definition and Eurostat definition.
• lin
  a data.frame containing the values of linearized variables of the GINI coefficient (in precentage) by domains or (if Dom is NULL) totals.
