    • Multitype spatial point patterns with hierarchical interactions 

      Särkkä, Aila; Högmander, Harri (University of Gothenburg, 1998-01-01)
      Multitype spatial point patterns with hierarchical interactions are considered. Here hierarchical interaction means directionality: Points on a higher level of hierarchy affect the locations of points on the lower levels, ...

    • Outlying observations and their influence on maximum pseudo-likelihood estimates of Gibbs point processes 

      Särkkä, Aila (University of Gothenburg, 1996-05-01)
      Maximum pseudo-likelihood estimation method is an attractive method to estimate interaction parameters of Gibbs point processes. A drawback of the method is that it tends to overestimate interaction if there is strong ...

    • Some interaction models for clustered point patterns 

      Grabarnik, Pavel; Särkkä, Aila (University of Gothenburg, 1998-08-01)
      We introduce a class of spatial point processes, interacting neighbour processes, where the density of the process can be written by means of local interactions between a point and subsets of its neighbourhood but where ...
