CoxShugart: Cox-Shugart measure of proportionality

In polrep: Calculate Political Representation Scores

Cox-Shugart measure of proportionality

Description

Calculate the Cox-Shugart measure of proportionality

Usage

CoxShugart(Z,R)

Arguments

Z	Population vector
R	Vector for the representatives

Details

This function calculates the Cox-Shugart measure of proportionality. It provides the slope of the regression line. For perfect representation, a score of 1 is calculated, for values smaller than 1, smaller groups in population are numerically over-represented. The Cox-Shugart measure of proportionality indicates the direction of mis-representation. It is also known as the regression index.

Value

A single score given the population and representatives
