Faltys, O., Hobza, T., Morales, D. (2022) "Small area estimation under area-level generalized linear mixed models", Communications in Statistics: Simulation and Computation, 51 (12):7404–7426

Ondřej Faltys, Tomáš Hobza (Czech Technical University in Prague) and  Domingo Morales (Operations Research Center, University Miguel Hernández of Elche) 
Abstract:This paper introduces a general area-level model-based formulation to small area estimation based on generalized linear mixed models. By applying an optimization algorithm to the Laplace approximation of the likelihood, the maximum likelihood estimators of the model […]

Meca, A., Sošić, G.(2022) "Strong Players and Stable Coalition Structures in PMAS Profit Game", Axioms, 11 (11):635

Ana Meca (Center of Operations Research, Miguel Hernández University of Elche) Greys Sošić (Marshall School of Business, University of Southern California)
Abstract: In a non-negative profit game that possesses a Population Monotonic Allocation Scheme (PMAS), being a member of a larger coalition implies that your profit cannot decrease. In this paper, we refer to such games […]

Camacho, J., Canovas, M.J., Parra, J. (2022) "From Calmness To Hoffman Constants For Linear Semi-Infinite Inequality Systems", SIAM Journal on Optimization, 32 (4):2859–2878

Jesús Camacho, María Josefa Cánovas and Juan Parra (Center of Operations Research, Miguel Hernández University of Elche) 
Abstract: In this paper we focus on different-global, semilocal, and local-versions of Hoffman-type inequalities expressed in a variational form. In a first stage our analysis is developed for generic multifunctions between metric spaces, and we finally deal with the […]
