gini: Compute Gini coefficient

In jcpernias/ec1047: Code and data for the EC1047 course

Description

Compute the generalized Gini coefficient of the distribution of y with weights weights. The parameter v is the degree of risk aversion. By default, this parameter equals 2 which corresponds with the original Gini coefficient.

Usage

gini(y, weights = NULL, v = 2)

Arguments

y	numerical vector.
weights	numerical vector of the same length as y with weights for each observation.
v	numerical scalar, degree of inequality aversion. It should be non-negative.

Details

Observations with zero weights are discarded before the computations begin.

Value

A numeric scalar.

Examples

gini(1:5)
gini(1:5, weights = 5:1)
gini(1:5, weights = 5:1, v = 3)
