Abstract:

Abstract: In the study of isotropic stationary spatial processes, a new nonparametric covariance estimation is proposed through its spectral representation. The method is based on estimation of the covariance's spectrum. A consistency result is presented, and numerical studies demonstrate its statistical efficiency with a fast computational time.
