weighted.atkinson: Atkinson Inequality Index

Description

This function computes the Atkinson inequality index for a vector of observations with corresponding weights.

Usage

weighted.atkinson(x, w = NULL, epsilon = 1, wscale = 1000)

Arguments

x

a vector of observations.

w

a vector of weights. If

epsilon

inequality aversion parameter as denoted by Atkinson (1970). The default is epsilon=1.

wscale

a scale by which the weights are adjusted such that can be rounded to natural numbers.

Value

• returns the selected Atkinson inequality index.
