LowerPartialMoments {fAssets}R Documentation

Estimation of Lower Partial Moments of Asset Sets

Description

A collection and description of functions for the estimation of lower partial moments from a tinme series of assets.

The functions are:

assetsLPM Computes LPMs and co-LPMs of a set of assets.

Usage

assetsLPM(x, tau, a, ...)

Arguments

a the value of the moment.
tau the target return.
x any rectangular time series object which can be converted by the function as.matrix() into a matrix object, e.g. like an object of class timeSeries, data.frame, or mts.
... optional arguments to be passed.

Value

assetsLPM
returns a list with two entries named mu and Sigma{Sigma}. The first denotes the vector of lower partial moments, and the second the co-LPM matrix. Note, that the output of this function can be used as data input for the portfolio functions to compute the LPM efficient frontier.
