The design-based Empirical Orthogonal Functions model : an alternative for the analysis of spatio-temporal data

Creator:: Munoz-Hernandez, Breda
Abstract:: Random processes are monitored over space and time by a network of stations distributed across a spatial region. Researchers have developed several analysis techniques to model the random process. Some of them require assumptions on the spatio-temporal variability of the process.
