Improving parametric Clarke and Wright algorithms by means of iterative empirically adjusted greedy heuristics / Corominas, Albert (Universitat Politècnica de Catalunya. Institut d'Organització i Control de Sistemes Industrials) ; García-Villoria, Alberto (Universitat Politècnica de Catalunya. Institute of Industrial and Control Engineering) ; Rafael Pastor, Rafael (Universitat Politècnica de Catalunya. Institute of Industrial and Control Engineering)
Since Clarke and Wright proposed their well-known savings algorithm for solving the Capacitated Vehicle Routing Problem, several enhancements to the original savings formula have been recently proposed, in the form of parameterisations. [...]

Regression analysis using order statistics and their concomitants / Rasoul Ziaei, Abdul (Islamic Azad University) ; Sheikhi, Ayyub (Shahid Bahonar University. Department of Statistics (Kerman, Iran)) ; Amirzadeh, Vahid (Shahid Bahonar University. Department of Statistics (Kerman, Iran))
In this work we derive the exact joint distribution of linear combinations of order statistics and linear combinations of their concomitants and some auxiliary variables in multivariate normal distribution. [...]

Decision making in kidney paired donation programs with altruistic donors / Li, Yijiang (Google Inc) ; Song, Peter X. -K. (University of Michigan. Department of Biostatistics) ; Leichtman, Alan B. (University of Michigan. Department of Internal Medicine) ; Rees, Michael A. (University of Toledo Medical Center (Toledo, Estats Units d'Amèrica)) ; Kalbﬂeisch, John D. (University of Michigan. Department of Biostatistics)
In recent years, kidney paired donation has been extended to include living non-directed or altruistic donors, in which an altruistic donor donates to the candidate of an incompatible donorcandidate pair with the understanding that the donor in that pair will further donate to the candidate of a second pair, and so on; such a process continues and thus forms an altruistic donor-initiated chain.

The asymptotic relative efficiency and the ratio of sample sizes when testing two different null hypotheses / Gómez Melis, Guadalupe (Universitat Politècnica de Catalunya. Departament d'Estadística i Investigació Operativa) ; Gómez-Mateu, Moisés (Universitat Politècnica de Catalunya. Departament d'Estadística i Investigació Operativa)
Composite endpoints, consisting of the union of two or more outcomes, are often used as the primary endpoint in time-to-event randomized clinical trials. Previously, Gómez and Lagakos provided a method to guide the decision between using a composite endpoint instead of one of its components when testing the effect of a treatment in a randomized clinical trial. [...]

Testing extreme value copulas to estimate the quantile / Bahraoui, Zuhair (Universitat de Barcelona. Departament d'Econometria) ; Bolancé, Catalina (Universitat de Barcelona. Departament d'Econometria) ; Pérez-Marín, Ana M.. (Universitat de Barcelona)
We generalize the test proposed by Kojadinovic, Segers and Yan which is used for testing whether the data belongs to the family of extreme value copulas. We prove that the generalized test can be applied whatever the alternative hypothesis. [...]
