If a portfolio has multiple assets, its volatility is calculated using a matrix. A variance-covariance matrix is computed for all the assets. The vector of the weights of the assets in the ...

when the diagonal elements of the true covariance matrix exhibit substantial variation, our method reduces the Mean Squared Error, compared with the OAS that targets an average variance. The ...

To describe the spread of the multivariate data, instead of a single variance value, you'd have a 2x2 covariance matrix. If you were looking at data with three values, such as men's (height, weight, ...

covDiag: Linear shrinkage towards diagonal matrix; the target preserves the diagonal of the sample covariance matrix and all the covariances ... Inverse Stein’s loss and Minimum Variance loss, called ...
