New methods for generating populations in Markov network based EDAs: Decimation strategies and model-based template recombination
Santana Hermida, Roberto
; ; (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 (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; (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
; Ferreira García, María Eva; 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 (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 (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; Illarramendi Echave, María Aránzazu ; 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 downloading and using COIN-OR for solving linear/integer optimization problems
Pérez Sainz de Rozas, Gloria; Garín Martín, María Araceli (2010)
The aim of this technical report is to present some detailed explanations in order to help to use the open source software for optimization COIN-OR. In particular, we describe how to download, install and use the corresponding ... -
On Downloading and Using CPLEX within COIN-OR for Solving Linear/Integer Optimization Problems
Pérez Sainz de Rozas, Gloria; Garín Martín, María Araceli (2011-11)
The aim of this technical report is to present some detailed explanations in order to use the solver CPLEX within COIN-OR environment. In particular, we describe how to download, install and use the corresponding source ... -
On monotonic core allocations for coalitional games whith veto players
(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 solving two stage stochastic linear problems by using a new approach, Cluster Benders Decomposition
Aranburu Laka, Larraitz; Escudero Bueno, Laureano F.; Garín Martín, María Araceli; Pérez Sainz de Rozas, Gloria (2010-11)
The optimization of stochastic linear problems, via scenario analysis, based on Benders decomposition requires to appending feasibility and/or optimality cuts to the master problem until the iterative procedure reaches the ... -
On the application of estimation of distribution algorithms to multi-marker tagging SNP selection
Santana Hermida, Roberto; ; Zaitlen, Noah; Eskin, Eleazar; (2009)
This paper presents an algorithm for the automatic selection of a minimal subset of tagging single nucleotide polymorphisms (SNPs) using an estimation of distribution algorithm (EDA). The EDA stochastically searches the ... -
On the Benefits of Including Age-structure in Harvest Control Rules
(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 ... -
On the economics of the "meeting competition defense" under the Robinson-Patman Act
Aguirre Pérez, Iñaki (Departamento de Fundamentos del Análisis Económico I, UPV/EHU, 2015-02-19)
In this paper we analyze the welfare effects of third-degree price discrimination when competitive pressure varies across markets. In particular, we study the economic aspects of the Robinson-Patman Act associated with the ... -
On the Informational Role of Term Structure in the U.S. Monetary Policy Rule
Vázquez Pérez, Jesús; María-Dolores, Ramón; Londoño Yarce, Juan Miguel (University of the Basque Country, Department of Foundations of Economic Analysis II, 2010-01)
This paper uses a structural approach based on the indirect inference principle to estimate a standard version of the new Keynesian monetary (NKM) model augmented with term structure using both revised and real-time data. ... -
On the optimal usage of labelled examples in semi-supervised multi-class classification problems
Ortigosa Hernández, Jonathan; Inza Cano, Iñaki; (2015-04-23)
In recent years, the performance of semi-supervised learning has been theoretically investigated. However, most of this theoretical development has focussed on binary classification problems. In this paper, we take it a ... -
On the strategic choice of spatial price policy: the role of the pricing game rules
Aguirre Pérez, Iñaki; Martín Arroyuelos, Ana María (2001-02)
In this paper, whe show that the strategic choice of spatial price policy under duopoly crucially depends on the rules of price competition. Thisse and Vives (1988) show that spatial price discrimination is a dominant ... -
On the strategic equivalence of multiple-choice test scoring rules
Espinosa Alejos, María Paz; Gardeazabal, Javier (University of the Basque Country, Department of Foundations of Economic Analysis II, 2005-12)
A disadvantage of multiple-choice tests is that students have incentives to guess. To discourage guessing, it is common to use scoring rules that either penalize wrong answers or reward omissions. These scoring rules are ... -
Ontologies for representation of folk song metadata
(2012)The digital management of collections in museums, archives, libraries and galleries is an increasingly important part of cultural heritage studies. This paper describes a representation for folk song metadata, based on the ... -
Optimal Correction for Guessing in Multiple-Choice Tests
Espinosa Alejos, María Paz; Gardeazabal, Javier (University of the Basque Country, Department of Foundations of Economic Analysis II, 2007-12)
Building on Item Response Theory we introduce students’ optimal behavior in multiple-choice tests. Our simulations indicate that the optimal penalty is relatively high, because although correction for guessing discriminates ...
