      Multiple imputation of time series: an application to the construction of historical price indexes 

      Tusell Palmer, Fernando Jorge ORCID (2005)
      Time series in many areas of application, and notably in the social sciences, are frequently incomplete. This is particularly annoying when we need to have complete data, for instance to compute indexes as a weighted average ...

      Music-Theoretic Estimation of Chords and Keys from Audio 

      Rocher, Thomas; Hanna, Pierre; Robine, Matthias; Conklin, Darrell (2012)
      This paper proposes a new method for local key and chord estimation from audio signals. This method relies primarily on principles from music theory, and does not require any training on a corpus of labelled audio files. ...

      Neutral candidates in approval and disapproval vote 

      González, Stéphane; Laruelle, Annick ORCID; Solal, Philippe (Fundamentos del Análisis Económico I, UPV/EHU, 2017-11-24)
      In this article, the question is to select the “best” candidates within a set of candidates when voters cast approval-disapproval ternary ballots. That is, three options are offered to voters: casting a vote “in favor”, a ...

      New methods for generating populations in Markov network based EDAs: Decimation strategies and model-based template recombination 

      Santana Hermida, Roberto ORCID; Mendiburu Alberro, Alexander; Lozano Alonso, José Antonio (2012-12-27)
      Methods for generating a new population are a fundamental component of estimation of distribution algorithms (EDAs). They serve to transfer the information contained in the probabilistic model to the new generated population. ...

      Non-Stationary Demand in a Durable Goods Monopoly 

      Usategui Díaz de Otalora, José María ORCID (University of the Basque Country, Department of Foundations of Economic Analysis II, 2006-01)
      In a context where demand for the services of a durable good changes over time, and this change may be uncertain, the paper shows that social welfare may be higher when the monopolist seller can commit to any future price ...

      Nonparametric estimation betas in the Market Model 

      Esteban González, María Victoria ORCID; Orbe Mandaluniz, Susan (2006)
      In this study an alternative nonparametric estimator to the Fama and MacBeth approach for the CAPM estimation is proposed. Betas and risk premiums are estimated simultaneously in order to increase the explanatory power of ...

      Nonparametric estimation of time varying parameters under shape restrictions 

      Orbe Mandaluniz, Susan; Ferreira García, María Eva ORCID; Rodríguez Poo, Juan M. (2001-01)
      In this paper we propose a new method to estimate nonparametrically a time varying parameter model when some qualitative information from outside data (e.g. seasonality) is available. In this framework we make two main ...

      Numerical Distribution Functions for Seasonal Unit Root Tests 

      Díaz-Emparanza Herrero, Ignacio ORCID (2011-12)
      When working with time series data observed at intervals smaller than a year, it is often necessary to test for the presence of seasonal unit roots. One of the most widely used methods for testing seasonal unit roots is ...

      Obtaining teaching expertise from F2F learning interactions 

      Ruiz, Samara; Urretavizcaya, Maite; Fernández de Castro, Isabel ORCID (2012)
      Learning environments are commonly used nowadays, but they exclude face-to-face interaction among teachers and students what is a successful basis of traditional education. On the other hand, in many cases teachers are ...

      On demand translation for querying incompletely aligned datasets 

      Torre-Bastida, Ana I.; Bermúdez de Andrés, Jesús ORCID; Illarramendi Echave, María Aránzazu ORCID; González, Marta (2014-12-01)
      More and more users aim at taking advantage of the existing Linked Open Data environment to formulate a query over a dataset and to then try to process the same query over different datasets, one after another, in order ...

      On monotonic core allocations for coalitional games whith veto players 

      Arin Aguirre, Francisco Javier; Feltkamp, Vincent (2007-10)
      We characterize a monotonic core concept defined on the class of veto balanced games. We also discuss what restricted versions of monotonicity are possible when selecting core allocations. We introduce a family of monotonic ...

      On the Benefits of Including Age-structure in Harvest Control Rules 

      Da Rocha, José María; Mato Amboage, Rosa (2014-08-27)
      This paper explores the benefits of including age-structure in the control rule (HCR) when decision makers regard their (age-structured) models as approximations. We find that introducing age structure into the HCR reduces ...
