Citicoline for the management of patients with traumatic brain injury in the acute phase: a systematic review and meta-analysis
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-02-01)
Article
Open AccessBackground: Citicoline or CDP-choline is a neuroprotective/neurorestorative drug used in several countries for the treatment of traumatic brain injury (TBI). Since the publication of the controversial COBRIT, the use of ... -
Thirty years of optimization-based SDC methods for tabular data
(2023-01)
Article
Open AccessIn 1966 Bacharach published in Management Science a work on matrix rounding problems in two-way tables of economic statistics, formulated as a network optimization problem. This is likely the first application of ... -
On solving large-scale multistage stochastic optimization problems with a new specialized interior-point approach
(2023-04)
Article
Open AccessA novel approach based on a specialized interior-point method (IPM) is presented for solving largescale stochastic multistage continuous optimization problems, which represent the uncertainty in strategic multistage and ... -
New interior-point approach for one- and two-class linear support vector machines using multiple variable splitting
(2022-09-29)
Article
Open AccessMultiple variable splitting is a general technique for decomposing problems by using copies of variables and additional linking constraints that equate their values. The resulting large optimization problem can be solved ... -
An algorithm for the microaggregation problem using column generation
(2022-08-01)
Article
Open AccessThe field of statistical disclosure control aims to reduce the risk of re-identifying an individual from disseminated data, a major concern among national statistical agencies. Operations Research (OR) techniques have been ... -
Measuring the effectiveness of online problem solving for improving academic performance in a probability course
(2022-01-13)
Article
Open AccessResearch on impact in student achievement of online homework systems compared to traditional methods is ambivalent. Methodological issues in the study design, besides of technological diversity, can account for this ... -

El valor P está obsoleto
(Elsevier, 2021-12-01)
Article
Open AccessEn esta píldora seguimos las guías de publicación1 y la declaración de la American Statistical Association (ASA)2. Pretendemos convencerle de que no use el valor de P (o P-value). No es tarea fácil. Pero seamos sinceros: ... -
Uso e interpretación de los intervalos de confianza
(Elsevier, 2021-12-01)
Article
Open AccessInterprete los intervalos de confianza como informativos de1: los valores poblacionales compatibles con los resultados observados; y2 la magnitud de la incertidumbre restante tras el estudio. Y si no existe un proceso de ... -
A specialized interior-point algorithm for huge minimum convex cost flows in bipartite networks
(Elsevier, 2021-05)
Article
Open AccessThe computation of the Newton direction is the most time consuming step of interior-point methods. This direction was efficiently computed by a combination of Cholesky factorizations and conjugate gradients in a specialized ... -
Recent advances in optimization techniques for statistical tabular data protection
(Elsevier, 2012-01-16)
Article
Open AccessOne of the main services of National Statistical Agencies (NSAs) for the current Information Society is the dissemination of large amounts of tabular data, which is obtained from microdata by crossing one or more categorical ... -
A new interior-point approach for large separable convex quadratic two-stage stochastic problems
(2020-11-03)
Article
Open AccessTwo-stage stochastic models give rise to very large optimization problems. Several approaches havebeen devised for efficiently solving them, including interior-point methods (IPMs). However, usingIPMs, the linking columns ...
