LowerPartialMoments {fAssets} | R Documentation |
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. |
assetsLPM(x, tau, a, ...)
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. |
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.
