19 p, 256.6 KB Glacial refugia and mid-Holocene expansion delineate the current distribution of Castanea sativa in Europe / Roces-Díaz, José V. (Centre de Recerca Ecològica i Aplicacions Forestals) ; Jiménez-Alfaro, Borja (Martin Luther University. Institute of Biology) ; Chytrý, Milan (Masaryk University. Department of Botany and Zoology) ; Díaz-Varela, Emilio R. (Universidade de Santiago de Compostela. ECOAGRASOC)
Areas of Quaternary refugia for tree species have been mainly delineated based on fossil records and phylogeography, but niche modelling can provide useful complementary information. Here we use palaeodistribution modelling to test the main hypotheses about the distribution of Castanea sativa in the Last Glacial Maximum (LGM) and the mid-Holocene in Europe. [...]

28 p, 328.9 KB Parameter estimation of Poisson generalized linear mixed models based on three different statistical principles : a simulation study / Casals, Martí (Universitat de Barcelona) ; Langohr, Klaus (Universitat Politècnica de Catalunya. Departament d'Estadística i Investigació Operativa) ; Carrasco, Josep Lluís (Universitat de Barcelona) ; Rönnegård, Lars (Dalarna University (Falun, Suècia). Statistics Unit)
Generalized linear mixed models are flexible tools for modeling non-normal data and are usefulfor accommodating overdispersion in Poisson regression models with random effects. Theirmain difficulty resides in the parameter estimation because there is no analytic solution for themaximization of the marginal likelihood. [...]

24 p, 154.6 KB Likelihood for random-effect models (invited article) / Lee, Youngjo (Seoul National University) ; Nelder, John A. (Imperial College London)
For inferences from random-effect models Lee and Nelder (1996) proposed to use hierarchical likelihood (h-likelihood). It allows inference from models that may include both fixed and random parameters. [...]
The new framework allows likelihood inferences to be drawn for a much wider class of models.
Per a la inferència en models amb efectes aleatoris Lee i Nelder (1996) proposaren utilitzar la versemblança jeràrquica (h-versemblanc¸a). Aquesta permet la inferència en models que presenten a la vegada paràmetres fixos i aleatoris. [...]

56 p, 1.7 MB Local Distance-Based Generalized Linear Models using the dbstats package for R / Boj del Val, Eva (Universitat de Barcelona. Departament de Matemàtica Econòmica, Financera i Actuarial) ; Delicado, Pedro (Universitat Politècnica de Catalunya. Departament d'Estadística i Investigació Operativa) ; Fortiana Gregori, Josep (Universitat de Barcelona) ; Esteve, Anna (Centre d'Estudis Epidemiològics sobre les ITS i Sida de Catalunya (CEEISCAT)) ; Caballé Mestres, Adrià (Universitat Politècnica de Catalunya) ; Xarxa de Referència en Economia Aplicada (XREAP)
This paper introduces local distance-based generalized linear models. These models extend (weighted) distance-based linear models firstly with the generalized linear model concept, then by localizing. [...]
