Guerrero, N.M., Aparicio, J., Valero-Carreras, D. (2022) “Combining Data Envelopment Analysis and Machine Learning”, Mathematics, 10 (6):909

Nadia Guerrero, Juan Aparicio and Daniel Valero (Operations Research Center, University Miguel Hernández of Elche) 
Abstract: Data Envelopment Analysis (DEA) is one of the most used non-parametric techniques for technical efficiency assessment. DEA is exclusively concerned about the minimization of the empirical error, satisfying, at the same time, some shape constraints (convexity and free disposability). Unfortunately, […]

Alcaraz, J., Labbé, M., Landete, M. (2022) “Support Vector Machine with feature selection: A multiobjective approach”, Expert Systems with Applications, 204:117485

Javier Alcaraz, Mercedes Landete (Operations Research Center, University Miguel Hernández of Elche) and Martine Labbé (Computer Science Department, Université Libre de Bruxelles, Belgium)
Abstract: Support Vector Machines are models widely used in supervised classification. The classical model minimizes a compromise between the structural risk and the empirical risk. In this paper, we consider the Support Vector […]

Soumaya Amassaghrou (University Miguel Hernández, DEcIDE doctorate program), Carlos Gutiérrez-Hita (Center of Operations Research, University Miguel Hernández and Universidad Antonio de Nebrija) and Vita Zhukova (Universidad Católica de Murcia)
Abstract: This paper analyses the liberalization process of the Moroccan mobile market since the beginning of the 21 st century. Our database ranges from 2004 to the […]

Burgard, J.P., Morales, D., Wölwer, A.-L. (2022) » Small area estimation of socioeconomic indicators for sampled and unsampled domains», AStA Advances in Statistical Analysis,

Jan Pablo Burgard, Anna Lena Wölwer  (Department of Economic and Social Statistics, Trier University) and Domingo Morales (Operations Research Center, University Miguel Hernández of Elche) and 
Abstract: Socioeconomic indicators play a crucial role in monitoring political actions over time and across regions. Income-based indicators such as the median income of sub-populations can provide information on the […]

Aparicio, J., Cordero, J.M., Ortiz, L. (2022) «Plausible values and their use in efficiency analyses with educational data», Applied Economics, 54 (29):3340–3352

Juan Aparicio, Lidia Ortiz (Universidad Miguel Hernández de Elche)  and José Manuel Cordero (Department of Economics, University of Extremadura)
Abstract: There is extensive literature focused on the evaluation of efficiency in the education sector, both at the micro level, analyzing the performance of students or schools, and at the macro level, exploring the behavior of regions […]

Guardiola, L.A., Meca, A., Puerto, J. (2022) «The effect of consolidated periods in heterogeneous lot-sizing games», TOP, 30 (2):380-404

Luis A. Guardiola (Departamento de Fundamentos del Análisis Económico, Universidad de Alicante), Ana Meca (I.U. Centro de Investigación Operativa, Universidad Miguel Hernández) and Justo Puerto (Mathematical Research Institute of the University of Seville (IMUS), Sevilla)
Abstract: We consider a cooperative game defined by an economic lot-sizing problem with heterogeneous costs over a finite time horizon, in […]

María Josefa Cánovas, Juan Parra (University Miguel Hernández of Elche), María Jesús Gisbert (Department of Statistics, Universidad Carlos III de Madrid) and Diethard Klatte (Institut für Betriebswirtschaftslehre, Universität Zürich)
Abstract: In this paper, we use a geometrical approach to sharpen a lower bound given in [5] for the Lipschitz modulus of the optimal value of (finite) […]

Batzelis, E., Blanes, J.M., Toledo, F.J., Galiano, V. (2022) "Noise-Scaled Euclidean Distance: A Metric for Maximum Likelihood Estimation of the PV Model Parameters", IEEE Journal of Photovoltaics, 12 (3):815–826

Efstratios Batzelis (University of Southampton), José M. Blanes, Francisco Javier Toledo and Vicente Galiano (Universidad Miguel Hernandez de Elche) 
Abstract: This article revisits the objective function (or metric) used in the extraction of photovoltaic (PV) model parameters. A theoretical investigation shows that the widely used current distance (CD) metric does not yield the maximum likelihood estimates […]

Morales, D., Krause, J., Burgard, J.P. (2022) "On the Use of Aggregate Survey Data for Estimating Regional Major Depressive Disorder Prevalence", Psychometrika, 87 (1):344–368

Domingo Morales (Operations Research Center, University Miguel Hernández of Elche) and Joscha Krause, Jan Pablo Burgard (Department of Economic and Social Statistics, Trier University) 
Abstract: Major depression is a severe mental disorder that is associated with strongly increased mortality. The quantification of its prevalence on regional levels represents an important indicator for public health reporting. In […]

Caballero, R., Marín-Rubio, P., Valero, J. (2022) «Existence and Characterization of Attractors for a Nonlocal Reaction–Diffusion Equation with an Energy Functional», Journal of Dynamics and Differential Equations, 34 (1):443–480

Rubén Caballero, José Valero (Centro de Investigación Operativa, Universidad Miguel Hernandez de Elche) and Pedro Marín (Dpto. Ecuaciones Diferenciales y Análisis Numérico, Universidad de Sevilla)
Abstract: In this paper we study a nonlocal reaction–diffusion equation in which the diffusion depends on the gradient of the solution. Firstly, we prove the existence and uniqueness of regular and […]
