Journal ArticleDOI
Equalities and Inequalities for Ranks of Matrices
TL;DR: In this paper, Equalities and Inequalities for Ranks of Matrices are discussed in the context of linear and multilinear algebras with respect to rank matrices.
Journal ArticleDOI
Hadamard products and multivariate statistical analysis
TL;DR: The Hadamard product of two matrices multiplied together elementwise is a rather neglected concept in matrix theory, and has found only brief and scattered application in statistical analysis.
Journal ArticleDOI
Bounds for eigenvalues using traces
TL;DR: In this paper, the modulus, real part, and the imaginary part of a linear combination of the ordered eigenvalues of a square complex matrix are obtained for the trace of a matrix and its square.
Journal ArticleDOI
The Equality of the Ordinary Least Squares Estimator and the Best Linear Unbiased Estimator
Simo Puntanen,George P. H. Styan +1 more
TL;DR: In this paper, the development of the several conditions for the OLS estimator to be best linear unbiased is presented, in a historical perspective, using generalized inverses and orthogonal projectors.
Journal ArticleDOI
Some properties of matrix partial orderings
TL;DR: In this article, the authors considered the problems of inheriting certain properties under a given ordering, preserving an ordering under some matrix multiplications, relationships between an ordering among direct (or Kronecker) and Hadamard products and the corresponding orderings between the factors involved, and ordering between generalized inverses of a given matrix.
