(Elsevier B.V., 2019)We introduce a novel approach to simulate Gaussian random fields defined over spheres of ℝ3. Through continuation we embed the process on the sphere in a nonstationary random field of ℝ3 to use a turning bands method. We ...

(Springer New York LLC, 2018)Nested covariance models, defined as linear combinations of basic covariance functions, are very popular in many branches of applied statistics, and in particular in geostatistics. A notorious limit of nested models is ...

An improved spectral turning-bands algorithm for simulating stationary vector Gaussian random fields (2016)We propose a spectral turning-bands approach for the simulation of second-order stationary vector Gaussian random fields. The approach improves existing spectral methods through coupling with importance sampling techniques. ...

(Springer, 2017)We review the origin and the meaning of the term seismomatics. In doing, this historical and recent seismicity of Chile is discussed. Moreover, the papers appearing in the special issue on seismomatics are briefly reviewed.

(Inst Mathematical Statistics, 2020)In spatial statistics, the screening effect historically refers to the situation when the observations located far from the predict and receive a small (ideally, zero) kriging weight. Several factors play a crucial role ...
