6 p, 1.2 MB Unequivocal signatures of the crossover to Anderson localization in realistic models of disordered quasi-one-dimensional materials / López Bezanilla, Alejandro (Los Alamos National Laboratory) ; Froufe Pérez, Luis S. (University of Fribourg. Department of Physics) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia) ; Sáenz, Juan José (IKERBASQUE)
The only unequivocal known criterion for single-parameter scaling Anderson localization relies on the knowledge of the full conductance statistics. To date, theoretical studies have been restricted to model systems with symmetric scatterers, hence lacking universality. [...]

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. [...]
