• closedAccess   Substationarity for spatial point processes 

      Zhang, Tonglin; Mateu, Jorge Elsevier Inc. (2019-05)
      This article aims to introduce the concept of substationarity for spatial point processes (SPPs). Substationarity is a new concept that has never been studied in the literature. Substationarity means that the distribution ...
    • closedAccess   Testing first-order spherical symmetry of spatial point processes 

      Zhang, Tonglin; Mateu, Jorge Institute of Statistical Science, Academia Sinica & International Chinese Statistical Association (2020)
      This study proposes a Kolmogorov-Smirnov-type test to assess the spherical symmetry of the first-order intensity function of a spatial point process (SPP). Spherical symmetry, which is an important assumption in the well ...
