  • Continuous time-varying kriging for spatial prediction of functional data: An environmental application 

    Giraldo, Ramón; Delicado Useros, Pedro Francisco; Mateu, Jorge (2008-07-07)
    Article
    Open Access
    Spatially correlated functional data is present in a wide range of environmental disciplines and, in this context, efficient prediction of curves is a key issue. We present an approach for spatial prediction based on the ...
  • Detección de rasgos en imágenes binarias mediante procesos puntuales espaciales marcados 

    Mateu, Jorge; Lorenzo, Gil (Institut d'Estadística de Catalunya, 2002)
    Article
    Open Access
    En este trabajo consideramos el problema de la detección de rasgos bajo la presencia de ruido en imágenes que tras un cierto tratamiento se reducen a binarias, por la presencia de dos tipos de elementos. Podemos encontrar ...
  • Geostatistics for functional data: an ordinary kriging approach 

    Giraldo, Ramón; Delicado Useros, Pedro Francisco; Mateu, Jorge (2007-06-11)
    Article
    Open Access
    We present a methodology to perform spatial prediction when measured data are curves. In particular, we propose both an estimator of the spatial correlation and a functional kriging predictor. We adapt an optimization ...
  • Modelización de la distribución espacial de quistes en el estómago de la marsopa mediante un proceso de Gibbs 

    Mateu, Jorge; Montes, F. (Francisco) (Institut d'estadística de Catalunya, 1998)
    Article
    Open Access
    En un trabajo previo (Balaguer et al., 1992) los autores estudiaron la distribución espacial de los quistes en el estómago de la marsopa para contrastar su compatibilidad con la hipótesis de aleatoriedad espacial completa ...
  • Statistical procedures for spatial point pattern recognition 

    Mateu, Jorge (Institut d'Estadística de Catalunya, 2002)
    Article
    Open Access
    Spatial structures in the form of point patterns arise in many different contexts, and in most of them the key goal concerns the detection and recognition of the underlying spatial pattern. Particularly interesting is the ...
  • Statistics for spatial functional data 

    Delicado Useros, Pedro Francisco; Giraldo, Ramón; Comas, Carles; Mateu, Jorge (2008-12)
    External research report
    Open Access
    Functional Data Analysis 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 data ...
