RPEIF

This package provides functions for computing the influence functions of risk and performance measures.


Installation

You can install the stable version on R CRAN.

install.packages("RPEIF", dependencies = TRUE)

You can install the development version from GitHub.

library(devtools) 
devtools::install_github("AnthonyChristidis/RPEIF")

Usage

# Sample Code
library(RPEIF)
# Loading the data
data(edhec, package = "PerformanceAnalytics")
colnames(edhec) = c("CA", "CTAG", "DIS", "EM","EMN", "ED", "FIA",
                    "GM", "LS", "MA", "RV", "SS", "FoF")
# Computing the IF of the returns (with outlier cleaning and prewhitening)
outIF <- IF(risk = "Mean",
            returns = edhec[,"CA"], evalShape = FALSE, retVals = NULL, nuisPars = NULL,
            IFplot = TRUE, IFprint = TRUE,
            prewhiten = TRUE,
            cleanOutliers = TRUE, cleanMethod = "locScaleRob", eff = 0.99)
