Lorenz.graphs: Graphs of concentration curves

In LorenzRegression: Lorenz and Penalized Lorenz Regressions

Graphs of concentration curves

Description

Lorenz.graphs traces the Lorenz curve of a response and the concentration curve of the response and each of a series of covariates.

Usage

Lorenz.graphs(formula, data, difference = FALSE, ...)

Arguments

formula	A formula object of the form response ~ other_variables. The form response ~ 1 is used to display only the Lorenz curve of the response.
data	A dataframe containing the variables of interest
difference	A logical determining whether the vertical axis should be expressed in terms of deviation from perfect equality. Default is FALSE.
...	Further arguments (see Section 'Arguments' in Lorenz.curve).

Value

A plot comprising

• The Lorenz curve of response

• The concentration curves of response with respect to each element of other_variables

Examples

data(Data.Incomes)
Lorenz.graphs(Income ~ Age + Work.Hours, data = Data.Incomes)
# Expressing now the vertical axis as the deviation from perfect equality
Lorenz.graphs(Income ~ Age + Work.Hours, data = Data.Incomes, difference = TRUE)
