    Two distinct ultrametrics, i.e., two hierarchical clustering schemes, may arise from a unique dissimilarity index when using a classification method. May be measured the distance between them by means of a distance index ...

  • The quadratic scoring rule as a basis for experiment comparision 

    Garcia Carrasco, Pilar (Universitat Politècnica de Barcelona. Centre de Càlcul, 1984-09)
    Article
    Accés obert
    In this paper, the role of strictly proper quadratic utility measures in Bayesian inference and experiment comparison is investigated. This utility function, which is not local, provides a good basis for the resolution of ...
