Juan Carlos Ferrando (Center of Operations Research, Miguel Hernández University of Elche) and Saak Gabriyelyan (Department of Mathematics, Ben-Gurion University of the Negev, Beer-Sheva)
Abstract: Let X be a Tychonoff space, and let S be a directed family of functionally bounded subsets of X containing all finite subsets of X. Denote by CTS(X) the space of […]

Guillén, M.D., Aparicio, J., Esteve, M. (2023) "Gradient tree boosting and the estimation of production frontiers", Expert Systems with Applications, 214:119134

María Dolores Guillén, Juan Aparicio and Miriam Esteve (Operations Research Center, University Miguel Hernández of Elche) 
Abstract: In production theory and engineering, a topic of interest is the determination of technical efficiency of firms from the estimation of a technology. By definition, a technology must satisfy a set of micro-economic postulates. Likewise, a valid estimator of […]

Lloret-Irles, D., Cabrera-Perona, V., Tirado-González, S., Segura-Heras, J.V. (2022) "Cyberbullying: Common Predictors to Cyber-Victimisation and Bystanding", International Journal of Environmental Research and Public Health, 19 (23):15750

Daniel Lloret-Irles, Víctor Cabrera-Perona, Sonia Tirado-González (Department of Health Psychology, Miguel Hernández University, Elche) and José Vicente Segura Heras(Operations Research Center, University Miguel Hernández of Elche) 
Abstract: Cyberbullying has increased worryingly in the last decade, becoming a mental health problem in adolescence. Research usually focuses on cyber-bullies or cyber-victims, overlooking that these roles may overlap (e.g., […]

Bikauskaite, A., Molina, I., Morales, D. (2022) "Multivariate mixture model for small area estimation of poverty indicators", Journal of the Royal Statistical Society. Series A: Statistics in Society, 185 (S2):S724–S755

Agne Bikauskaite (Business Statistics Division, Eurostat, Luxembourg), Isabel Molina (Department of Statistics, University of Carlos III de Madrid) and Domingo Morales (Operations Research Center, University Miguel Hernández of Elche) 
Abstract: When disaggregation of national estimates in several domains or areas is required, direct survey estimators, which use only the domain-specific survey data, are usually design-unbiased even […]

Ferrando, J.C., Kąkol, J. (2022) "Distinguished vector-valued continuous function spaces and injective tensor products", Bulletin of the Belgian Mathematical Society – Simon Stevin, 28 (5):709–721

Juan Carlos Ferrando (Operations Research Center, University Miguel Hernández of Elche) and Jerzy Kąkol (Departamento de Física Teórica, Facultad de Ciencias Físicas, Universidad Complutense, Madrid)
Abstract: The paper continues the study on the distinguished property of the space Cp(X)Cp(X) (of real-valued continuous functions over a Tychonoff space XX in the pointwise topology) under the formation of tensor products towards the following […]

Alcaraz, J., Monge, J.F., Ramón, N. (2022) «Ranking ranges in cross-efficiency evaluations: A metaheuristic approach», Journal of the Operational Research Society, 73 (4):779–793

Javier Alcaraz, Juan Francisco Monge and Nuria Ramón (Center of Operations Research (CIO), Miguel Hernández University of Elche) 
Abstract: In the cross-efficiency evaluation, the existence of alternative optima for weights represents an inconvenience because the ranking obtained depends on the weights used. Alcaraz et al. (2013) design an algorithm that provides a range of positions for […]

Alcaraz, J., Anton-Sanchez, L., Monge, J.F. (2022) “The Concordance Test, an Alternative to Kruskal-Wallis Based on the Kendall- τ Distance: An R Package”, R Journal, 14 (2):26-53

Javier Alcaraz, Laura Anton-Sanchez, Juan Francisco Monge (Operations Research Center, University Miguel Hernández of Elche)
Abstract: The Kendall rank correlation coefficient, based on the Kendall-τ� distance, is used to measure the ordinal association between two measurements. In this paper, we introduce a new coefficient also based on the Kendall-τ� distance, the Concordance coefficient, and a test to measure whether […]

Juan Aparicio, & Miriam Esteve (2023). How to peel a data envelopment analysis frontier: A cross-validation-based approach. Journal of the Operational Research Society, 74, 2558-2572.

Juan Aparicio (Miguel Hernández University of Elche; Valencian Graduate School and Research Network of Artificial Intelligence (valgrAI), and Miriam Esteve (Miguel Hernández University of Elche)
Abstract:
Data Envelopment Analysis (DEA) presents the typical characteristics of a data-driven approach with the specific objective of determining technical efficiency and production frontiers in Engineering and Microeconomics. However, by construction, the […]
