Atkinson Inequality Index

Description

Calculating the Atkinson Inequality Index e.g. with respect to regional income

Usage

atkinson(x, epsilon = 0.5, na.rm = TRUE)

Arguments

x

A numeric vector (e.g. dataset of regional income)

epsilon

A single value of the \epsilon weighting coefficient (default: at.epsilon = 0.5)

na.rm

logical argument that indicates whether NA values should be excluded before computing results

Details

The Atkinson Inequality Index (AI) varies between 0 (no inequality/concentration) and 1 (complete inequality/concentration). It can be used for economic inequality and/or regional disparities (Portnov/Felsenstein 2010).

Value

A single numeric value of the Atkinson Inequality Index (0 < AI < 1).
