BLResult-class {BLCOP}

Class "BLResult": posterior of a market distribution in the Black-Litterman sense

Description

This class holds the posterior market mean and variance-covariance matrix calculated from some prior and set of views. The original views are also returned.

Objects from the Class

Objects can be created by calls of the form new("BLResult", ...). However, it is intended that they be created by the function posteriorEst(or wrappers to that function).

Slots

views:

Object of class "BLViews". These are the original views used to calculate this posterior

tau:

Object of class "numeric". The value of "tau" used

priorMean:

Object of class "numeric": prior vector of market means

priorCovar:

Object of class "matrix": prior of the variance-covariance

posteriorMean:

Object of class "numeric": posterior mean

posteriorCovar:

Object of class "matrix": posterior variance-covariance

kappa:

Object of class "logical": logical flag indicating whether or not confidences-in-views were ignored.
