    • 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 ...

    • openAccess   Geofd: An R Package for Function-Valued Geostatistical Prediction 

      Giraldo, Ramón; Mateu, Jorge; Delicado, Pedro Universidad Nacional de Colombia (2015-12)
      Spatially correlated curves are present in a wide range of applied disciplines. In this paper we describe the R package geofd which implements ordinary kriging prediction for this type of data. Initially the curves ...

    • 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   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 ...
