Abstract

For a singular random matrix X, we find the Jacobians associated to the following decompositions: QR, Polar, Singular Value (SVD), L'U, L'DM and modified QR (QDR). Similarly, for the cross-product matrix S=X'X we find the Jacobians of the Spectral, Cholesky's, L'DL and symmetric nonnegative definite square root decompositions.
