colpafs: Many PaF income polarization indices

In DER: Income Polarization Index

Many PaF income polarization indices

Description

Many PaF income polarization indices

Usage

colpafs(y, a)

Arguments

y	A numeric matrix with income data. The PaF index will be computed for each column sperately.
a	The value of \alpha, a number between 0.25 and 1.

Details

The function compute the PaF index of Duclos, Esteban and Ray (2004) for a specific value of \alpha, for each column of the matrix.

Value

A matrix, where each row contains the PaF index, the alienation (twice the Gini index) and identification components and 1 + the normalized covariance.
