The cgeostat software for analyzing complex-valued random fields

Given a vectorial data set in two dimensions,a representation on a complex domain is often convenient. this representation is rarely considered in geostatistics,although interesting applications can be found in environmental sciences and meteorology (e.g.,for wind fields). in such a case,some computational difficulties are related to the lack of software for estimating and modeling a complex covariance function,for predicting complex variables as well as for representing the output results. in this paper,the new fortran software cgeostat for geostatistical analysis of complex-valued random fields is presented and an application is demonstrated. © 2017,american statistical association. all rights reserved.
