A Note on Eigenstructure of a Spatial Design Matrix In R1 Kim Hyoung-Moon; Tarazaga Pablo;
Eigenstructure of a spatial design matrix of Matheron's variogram estimator in is derived. It is shown that the spatial design matrix in with n/2h < n has a nice spectral decomposition. The mean, variance, and covariance of this estimator are obtained using the eigenvalues of a spatial design matrix. We also found that the lower bound and the upper bound of the normalized Matheron's variogram estimator.
