Wolfson polarization index — md_compute

Compute the Wolfson polarization index for microdata.

Usage

md_compute_polarization(welfare, weight, gini, mean, median)

welfare: numeric: A vector of income or consumption values
weight: numeric: A vector of population weights, optional, a vector of 1s if not specified.
gini: numeric: Gini. Output of md_compute_gini().
mean: numeric: A value with the mean. Optional.
median: numeric: Median. Output of md_compute_median().
