64 p, 1.4 MB Hierarchical models with normal and conjugate random effects : a review / Molenberghs, Geert (Universiteit Hasselt (Hasselt, Bèlgica). I-BioStat) ; Verbeke, Geert (KU Leuven (Leuven, Bèlgica). I-BioStat) ; Demétrio, Clarice G. B. (Universidade de São Paulo)
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. [...]

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. [...]

14 p, 107.2 KB Some discrete exponential dispersion models : poisson-tweedie and hinde-demétrio classes / Kokonendji, Célestin C. (University of Pau-LMA) ; Dossou-Gbété, Simplice (University of Pau-LMA) ; Demétrio, Clarice G. B. (University of S˜ao Paulo)
In this paper we investigate two classes of exponential dispersion models (EDMs) for overdispersed count data with respect to the Poisson distribution. The first is a class of Poisson mixture with positive Tweedie mixing distributions. [...]

15 p, 137.4 KB Indirect inference for survival data / Turnbull, Bruce W. (Cornell University) ; Jiang, Wenxin (Cornell University)
In this paper we describe the so-called "indirect" method of inference, originally developed from the econometric literature, and apply it to survival analyses of two data sets with repeated events. This method is often more convenient computationally than maximum likelihood estimation when handling such model complexities as random effects and measurement error, for example; and it can also serve as a basis for robust inference with less stringent assumptions on the data generating mechanism. [...]

34 p, 450.0 KB Mixture of bivariate Poisson regression models with an application to insurance / Bermúdez, Lluís (Universitat de Barcelona. Departament de Matemàtica Financera i Actuarial) ; Karlis, Dimitris (Athens University of Economics and Business) ; Xarxa de Referència en Economia Aplicada (XREAP)
In a recent paper Bermúdez [2009] used bivariate Poisson regression models for ratemaking in car insurance, and included zero-inflated models to account for the excess of zeros and the overdispersion in the data set. [...]
