This book presents the reader with new operators and matrices that
arise in the area of matrix calculus. The properties of these
mathematical concepts are investigated and linked with zero-one
matrices such as the commutation matrix. Elimination and
duplication matrices are revisited and partitioned into
submatrices. Studying the properties of these submatrices
facilitates achieving new results for the original matrices
themselves. Different concepts of matrix derivatives are presented
and transformation principles linking these concepts are obtained.
One of these concepts is used to derive new matrix calculus
results, some involving the new operators and others the
derivatives of the operators themselves. The last chapter contains
applications of matrix calculus, including optimization,
differentiation of log-likelihood functions, iterative
interpretations of maximum likelihood estimators and a Lagrangian
multiplier test for endogeneity.
