The G4 inverse is computed using the eigenvalue decomposition , where Z is the orthogonal matrix of eigenvectors and is the diagonal matrix of eigenvalues, . The G4 inverse of H is set to where the ...

This paper proposes a novel shrinkage estimator for high-dimensional covariance matrices by extending the Oracle Approximating Shrinkage (OAS) of Chen et al. (2009) to target the diagonal elements of ...

where matrix is a square nonsingular matrix. The INV function produces a matrix that is the inverse of matrix, which must be square and nonsingular. However, the SOLVE function is more accurate and ...

The S matrix is special because it is diagonal and so its inverse is easy to compute -- just invert the diagonal elements. The Vh matrix (sometimes named Vt) is special because its inverse equals the ...
