A Branching-selection process related to censored Galton-Walton processes
نویسندگان
چکیده
We obtain the asymptotics for the speed of a particular case of a particle system with branching and selection introduced by Bérard and Gouéré (2010). The proof is based on a connection with a supercritical Galton-Watson process censored at a certain level. Résumé Nous étudions un cas particulier de système de particules avec branchement et sélection introduit par Bérard et Gouéré (2010). Nous obtenons l’asympotique pour la vitesse, en remarquant un lien avec un processus de Galton-Watson surcritique censuré à un certain niveau. MSC: 60J80

Monitoring the censored lognormal reliability data in a three-stage process using AFT model
Improving the product reliability is the main concern in both manufacturing and service processes which is obtained by monitoring the reliability-related quality characteristics. Nowadays, products or services are the result of processes with dependent stages referred to as multistage processes. In these processes, the quality characteristic in each stage is affected by the quality characterist...
متن کاملBranching Processes
The study of branching processes began in the 1840s with Irénée-Jules Bienaymé, a probabilist and statistician, and was advanced in the 1870s with the work of Reverend Henry William Watson, a clergyman and mathematician, and Francis Galton, a biometrician. In 1873, Galton sent a problem to the Educational Times regarding the survival of family names. When he did not receive a satisfactory answe...
متن کاملLévy processes and continuous-state branching processes: part III
Originating in part from the concerns of the Victorian British upper classes that aristocratic surnames were becoming extinct, the theory of branching processes now forms a cornerstone of classical applied probability. Some of the earliest work on branching processes dates back to Galton and Watson in 1874, [25]. However, approximately 100 years later, it was discovered in [13] that the less we...
متن کاملBranching Processes in Stochastic Environments
This paper is concerned with two simple models for branching processes in stochastic environments. The models are identical to the model for the classical Galton-Watson branching process in all respects but one. In the family-tree language commonly used to describe branching processes, that difference is that the probability distribution for the number of offspring of an object changes stochast...
