Correlation Matrix Definiteness. When simulating a model, some random variable inputs may be correlated. One way to introduce this correlation into the simulation is by rank order correlation. In this method a correlation matrix is used to define the correlation structure. The correlation matrix definiteness is important.

I know these two criteria: A symmetric matrix is positive definite iff all eigenvalues are greater zero, positive semidefinite iff alle ...

Definite, Semi-Definite and Indefinite Matrices. We are about to look at an important type of matrix in multivariable calculus known as Hessian Matrices.

For a 2-by-2 matrix, the determinant is calculated by subtracting the reverse diagonal from the main diagonal, which is known as the Leibniz formula. The determinant of the product of matrices is equal to the product of determinants of those matrices, so it may be beneficial to decompose a matrix into simpler matrices, calculate the individual ...
