Exp_Map_Barycenter_Method: Numerical implementation of the Exponential map

Description

This function implements the Exponential map to calculate \(\hat{F}_t(u)\) for all \(u\) in the cdf/pdf support

Usage

Exp_Map_Barycenter_Method(density.grid, forecast, cdf)

Value

A numeric vector that contains \(\hat{F}_t(u)\) evaluated over density.grid

Arguments

density.grid

The values where the cdf \(\hat{F}\) is evaluated

forecast

A vector that contains the WAR(p) model forecast result

cdf

The quantile grid used in forecasting
