Affluence Indices


Allows to compute the affluence (richness) indices (affluence gap, income share of the top p %, richness headcount ratio, concave and convex measures of affluence) and to construct the confidence intervals for affluence indices. The richness line is defined by the user as multiple of the income median. Additionally, this package allows also to compute the Wolfson polarization index.
