      Matallín Sáez, Juan Carlos; Soler-Dominguez, Amparo; de Mingo-López, Diego Víctor Palgrave Macmillan (2021-06-01)
      This study shows how investing in mutual funds involves an additional risk, which we call management risk as a consequence of the uncertainty in the results of active management. To address this issue, we analyze a sample ...

      Alonso Gutiérrez, David; Nikos, Dafnis; Hernández Cifre, Maria Ángeles; Prochno, Joscha Indiana University Mathematics Journal (2014)
      In this paper we introduce a new sequence of quantities for random polytopes. Let KN = conv{X1, . . . ,XN} be a random polytope generated by independent random vectors uniformly distributed in an isotropic convex body K ...

      Mateu, Jorge; Schoenberg, Frederic P.; Diez, David M.; González Monsalve, Jonatan Andrey; Lu, Weipeng Wiley (2015-03)
      This paper presents a collection of dissimilarity measures to describe and then classify spatial point patterns when multiple replicates of different types are available for analysis. In particular, we consider a range of ...
    • openAccess   On Metrics for Location-Aware Games 

      Rodríguez-Pupo, Luis E.; Casteleyn, Sven; Granell, Carlos MDPI (2017-09)
      Metrics are important and well-known tools to measure users’ behavior in games, and gameplay in general. Particularities of location-aware games—a class of games where the player’s location plays a central role-demand ...
