Since its appearance in the 1990s, horizontal collaboration (HC) practices have revealed themselves as catalyzers for optimizing the distribution of goods in freight transport logistics. After introducing the main concepts related to HC, this paper offers a literature review on the topic and provides a classification of best practices in HC. [...]

This paper has two complementary objectives: on the one hand, it introduces the EURO method for the estimation of (regional) Social Accounting Matrices. This method is widely used by Eurostat for the estimation of missing national Supply, Use and Input-output tables but it has not been used before within the context of social accounting matrices or of regional statistics and/or regional impact analyses.

Departamento de Estadística) ; Morales Socuéllamos, Javier (Universidad Miguel Hernández. Departamento de Estadística) ; Barber, Antoni (IDENTIA Institute)
A methodological approach for modelling the spatial distribution of bioclimatic indices is proposed in this paper. The value of the bioclimatic index is modelled with a hierarchical Bayesian model that incorporates both structured and unstructured random effects. [...]

22 p, 599.9 KB A bivariate response model for studying the marks obtained in two jointly-dependent modules in higher education / Gómez-Déniz, Emilio (Universidad de las Palmas de Gran Canaria. Departamento de Métodos Cuantitativos) ; Dávila Cárdenes, Nancy (Universidad de las Palmas de Gran Canaria. Departamento de Métodos Cuantitativos) ; García Artiles, María Dolores (Universidad de las Palmas de Gran Canaria. Departamento de Métodos Cuantitativos)
We study the factors which may affect students' marks in two modules, mathematics and statistics, taught consecutively in the first year of a Business Administration Studies degree course. For this purpose, we introduce a suitable bivariate regression model in which the dependent variables have bounded support and the marginal means are functions of explanatory variables. [...]

Molenberghs, Verbeke, and Demétrio (2007) and Molenberghs et al. (2010) proposed a general framework to model hierarchical data subject to within-unit correlation and/or overdispersion. The framework extends classical overdispersion models as well as generalized linear mixed models. [...]
