Small area estimation of labour force indicators under a multinomial model with correlated time and area effects
(Wiley-Blackwell Publishing Ltd., 2014-09-30)
[Abstract] The aim of the paper is the estimation of small area labour force indicators like totals of employed and unemployed people and unemployment rates. Small area estimators of these quantities are derived from four ...
Estudio métrico sobre la actividad investigadora usando el software libre R: el caso del sistema universitario gallego
(Universidad Nacional Autónoma de México, 2017)
[Resumen] Este trabajo representa una nueva alternativa para el estudio, clasificación y comparación de la producción científica de centros de investigación, utilizando las funciones de tratamiento de datos del paquete ...
Cooperation on capacitated inventory situations with fixed holding costs
(Elsevier, 2015-03-16)
[Abstract] In this paper we analyze a situation in which several firms deal with inventory problems concerning the same type of product. We consider that each firm uses its limited capacity warehouse for storing purposes ...
Prediction of forest fires occurrences with area-level Poisson mixed models
(Academic Press, 2015-05-01)
[Abstract] The number of fires in forest areas of Galicia (north-west of Spain) during the summer period is quite high. Local authorities are interested in analyzing the factors that explain this phenomenon. Poisson ...
Empirical best prediction under area-level Poisson mixed models
(Springer, 2015-12-19)
[Abstract] The paper studies the applicability of area-level Poisson mixed models to estimate small area counting indicators. Among the available procedures for fitting generalized linear models, the method of moments (MM) ...
A posteriori error analysis of an augmented mixed formulation in linear elasticity with mixed and Dirichlet boundary conditions
(Elsevier BV, 2011-01)
[Abstract] We develop a residual-based a posteriori error analysis for the augmented mixed methods introduced in and for the problem of linear elasticity in the plane. We prove that the proposed a posteriori error estimators ...
Burned area prediction with semiparametric models
(CSIRO Publishing, 2016-04-27)
[Abstract] Wildfires are one of the main causes of forest destruction, especially in Galicia (north-west Spain), where the area burned by forest fires in spring and summer is quite high. This work uses two semiparametric ...
Evaluation of Depression in Subacute Low Back Pain: A Case Control Study
(American Society of Interventional Pain Physicians, 2017)
[Abstract] Low back pain (LBP) is the most common musculoskeletal disorder affecting the general population and it is believed to be associated with depression. The study aim was to describe and compare the impact in a ...
Comparing conditional survival functions with missing population marks in a competing risks model
(Elsevier, 2016-11-25)
[Abstract] In studies involving nonparametric testing of the equality of two or more survival distributions, the survival curves can exhibit a wide variety of behaviors such as proportional hazards, early/late differences, ...
Nonparametric incidence estimation and bootstrap bandwidth selection in mixture cure models
(Elsevier, 2017-01)
[Abstract]: A completely nonparametric method for the estimation of mixture cure models is proposed. A nonparametric estimator of the incidence is extensively studied and a nonparametric estimator of the latency is presented. ...
