calcAtkinson: Atkinson Index of Inequality

In IC2: Inequality and Concentration Indices and Curves

Description

Computes an Atkinson measure of inequality within a vector.

Usage

calcAtkinson(x, w = NULL, epsilon = 1)

Arguments

x	Numeric vector with non-negative values (strictly positive when epsilon=1)
w	Numeric vector of sampling weigths (optional)
epsilon	Parameter of the Atkinson index (must be strictly positive)

Value

A list of class "ICI" with components:

ineq	a list with components Atk (value of inequality index) and epsilon (value of parameter)
nas	a list with NA counts, including components xNA, wNA and totalNA
