Evaluation of Tests for Separability and Symmetry of Spatio-temporal Covariance Function
Journal of Statistical Research of Iran
In recent years, some investigations have been carried out to examine the assumptions like stationarity, symmetry and separability of spatio-temporal covariance function; which would considerably simplify fitting a valid covariance model to the data by parametric and nonparametric methods. In this article, assuming a Gaussian random field, we consider the likelihood ratio separability test, a variety of nonparametric and spectral tests of symmetry and also separability of spatio-temporaldoi:10.18869/acadpub.jsri.8.1.1 fatcat:uv2vwj54j5am7jxjm355tqblje
