get_rif_gini: Estimate RIF of Gini coefficient

In rifreg: Estimate Recentered Influence Function Regression

Estimate RIF of Gini coefficient

Description

Compute the recentered influence function (RIF) of a weighted Gini coefficient.

Usage

get_rif_gini(dep_var, weights)

Arguments

dep_var	values of a non-negative continuous dependent variable
weights	numeric vector of non-negative observation weights, hence of same length as dep_var.

Value

A data frame with one column containing the RIF of the Gini coefficient for each observation.
