    • closedAccess   A second order approach to analyse spatial point patterns with functional marks 

      Comas Rodríguez, Carlos; Delicado, Pedro; Mateu, Jorge Springer (2011-11)
      A new second order statistic based on the mark correlation function to analyse spatial point patterns with functional marks is presented. An edge corrected estimator is defined and illustrated through a ...

    • closedAccess   A second-order test to detect spatio-temporal anisotropic effects in point patterns 

      Comas Rodríguez, Carlos; Conde, J.; Mateu, Jorge Taylor & Francis (2018)
      Second-order spatio-temporal orientation methods provide a natural tool for the analysis of anisotropic spatio-temporal point process data. In this paper, we generalize a method based on the spatial point pair orientation ...

    • closedAccess   On tree intensity estimation for forest inventories: Some statistical issues 

      Comas Rodríguez, Carlos; Mateu, Jorge; Delicado, Pedro Wiley (2011-11)
      The effect of the plot shape, number of subplots and their spatial arrangement on the sample variance for spatially explicit point populations is analysed for a simple intensity estimator. We derive the sample variance ...

    • closedAccess   Second-order analysis of anisotropic spatiotemporal point process data 

      Comas Rodríguez, Carlos; Rodríguez-Cortés, Francisco Javier; Mateu, Jorge Wiley (2015-02)
      Second-order orientation methods provide a natural tool for the analysis of spatial point process data. In this paper, we extend to the spatiotemporal setting the spatial point pair orientation distribution function. The ...

    • closedAccess   Space-time dependence dynamics for birth-death point processes 

      Comas Rodríguez, Carlos; Mateu, Jorge Elsevier (2008)
      This paper analyses the space-time interdependency of a spatially explicit birth-death process based on the intensity function. Based on intensity functions, these formulations can be, to some extent, analytically solved ...

    • closedAccess   Statistical inference for Gibbs point processes based on field observations 

      Comas Rodríguez, Carlos; Mateu, Jorge Wiley (2011-02)
      Forest inventories are mostly based on field observations, and complete records of spatial tree coordinates are seldom taken. The lack of individual coordinates prevents the use of well stablised statistical inference tools ...

    • closedAccess   Statistics for spatial functional data: some recent contributions 

      Delicado, Pedro; Giraldo, Ramón; Comas Rodríguez, Carlos; Mateu, Jorge John Wiley & Sons, Ltd. (2010)
      Functional data analysis (FDA) is a relatively new branch in statistics. Experiments where a complete function is observed for each individual give rise to functional data. In this work we focus on the case of functional ...
