DiversificationR (version 0.1.0)

f_diversification_measurement: Function computing portfolio diversification measures

Description

This function computes several portfolio diversification measures: Portfolio Diversification Index (PDI), Diversification Ratio (DR), Diversification Delta (DD) and Diversification Delta Star (DD*).

Usage

f_diversification_measurement(v_input_weights, m_input_returns, c_input_method)

Arguments

v_input_weights

A vector of numerical values (asset weights)

m_input_returns

A matrix of numerical values (asset returns)

c_input_method

A character value (name of the diversification measure)

Value

result

A numeric value
