Covariance Matrix Estimation Via Network Structure

SSRN Electronic Journal, 2016
In this article, we employ a regression formulation to estimate the high dimensional covariance matrix for a given network structure. Using prior information contained in the network relationships, we model the covariance as a polynomial function of the symmetric adjacency matrix.

Covariance Matrix Estimation in Complex Surveys

The Egyptian Statistical Journal, 1989
Summary: An estimator of the asymptotic covariance matrix of the vector of second- order sample moments under cluster sampling design is derived by the Taylor expansion method. The form of the estimator under stratified cluster sampling design is obtained as well.

Covariant method for soliton matrix elements

Physical Review D, 1986
We construct field-theory wave functions for soliton and other collective states in field theory. The formalism is covariant, incorporates zero modes, and the states can be directly related to states postulated in the standard Hamiltonian quantization procedures.
