coskewnessSF: Coskewness Matrix Estimate

In PortfolioAnalytics: Portfolio Analysis, Including Numerical Methods for Optimization of Portfolios

Description

Estimate coskewness matrix using a single factor statistical factor model

Usage

coskewnessSF(beta, stockM3, factorM3)

Arguments

beta	vector of length N or (N x 1) matrix of factor loadings (i.e. the betas) from a single factor statistical factor model
stockM3	vector of length N of the 3rd moment of the model residuals
factorM3	scalar of the 3rd moment of the factor realizations from a single factor statistical factor model

Details

This function estimates an (N x N^2) coskewness matrix from a single factor statistical factor model with k=1 factors, where N is the number of assets.

Value

(N x N^2) coskewness matrix
