The Pareto IV power series cure rate model with applications / Gallardo, Diego (Universidad de Atacama (Copiapó, Xile). Departamento de Matemática) ; Gómez, Yolanda (Universidad de Atacama (Copiapó, Xile). Departamento de Matemática) ; Arnold, Barry C. (University of California. Statistics Department) ; Gómez, Héctor W. (Universidad de Antofagasta (Antofagasta, Xile). Departamento de Matemáticas)
Cutaneous melanoma is thought to be triggered by intense, occasional exposure to ultraviolet radiation, either from the sun or tanning beds, especially in people who are genetically predisposed to the disease. [...]

Two alternative estimation procedures for the negative binomial cure rate model with a latent activation scheme / Gallardo, Diego (Universidad de Antofagasta (Chile). Departamento de Matemáticas) ; Bolfarine, Heleno (Universidade de São Paulo. Departamento de Estatística)
In this paper two alternative estimation procedures based on the EM algorithm are proposed forthe flexible negative binomial cure rate model with a latent activation scheme. The Weibull modelas well as the log-normal and gamma distributions are also considered for the time-to-event datafor the non-destroyed cells. [...]

Estimation in the Birnbaum-Saunders distribution based on scale-mixture of normals and the EM-algorithm / Balakrishnan, Narayanaswamy ; Leiva, Víctor ; Sanhueza, Antonio ; Vilca, Filidor
Scale mixtures of normal (SMN) distributions are used for modeling symmetric data. Members of this family have appealing properties such as robust estimates, easy number generation, and efficient computation of the ML estimates via the EM-algorithm. [...]

Survival analysis with coarsely observed covariates / Feodor Nielsen, Soren (University of Copenhagen)
In this paper we consider analysis of survival data with incomplete covariate information. We model the incomplete covariates as a random coarsening of the complete covariate, and an overview of the theory of coarsening at random is given. [...]

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. [...]
