• openAccess   Archimedean spectral densities for nonstationary space-time 

      Porcu, Emilio; Gregori, Pablo; Mateu, Jorge Academia Sinica. Institute of Statistical Science (2009)
      In this work we investigate methods for modelling space-time nonstationary data. We combine the approaches based on spatial adapting and spectral tempering of spectral densities with the desirable features of Archimedean ...
