Stochastic models for phylogenetic trees on higher-order taxa.
Simple stochastic models for phylogenetic trees on species have been well studied. But much paleontology data concerns time series or trees on higher-order taxa, and any broad picture of relationships between extant groups requires use of higher-order taxa. A coherent model for trees on (say) genera should involve both a species-level model and a model for the classification scheme by which spe...
متن کاملStochastic Models for Speciation Events in Phylogenetic trees
Hiermit erkläre ich, dass ich die Diplomarbeit selbständig angefertigt und nur die angegebenen Quellen und Hilfsmittel verwendet habe. Acknowledgements First and foremost, I would like to thank my supervisor Mike Steel for making it possible for me to come to New Zealand, for the great support throughout my stay, for suggesting great problems to work on and for very helpful discussions and advi...
متن کاملHigher order variation and stochastic volatility models
Limit distribution results on quadratic and higher order variation quantities are derived for certain types of continuous local martingales, in particular for a class of OU-based stochastic volatility models. Some key words: Mixed asymptotic normality; Realised volatility; Quadratic variation.
متن کاملBayesian Models for Phylogenetic trees
introduction: inferring genetic ancestry of different species is a current challenge in phylogenetics because of the immense raw biological data to be analyzed. computational techniques are necessary in order to parse and analyze all of such data in an efficient but accurate way, with many algorithms based on statistical principles designed to provide a best estimate of a phylogenetic topology....
متن کاملA stochastic model for phylogenetic trees
We propose the following simple stochastic model for phylogenetic trees. New types are born and die according to a birth and death chain. At each birth we associate a fitness to the new type sampled from a fixed distribution. At each death the type with the smallest fitness is killed. We show that if the birth (i.e. mutation) rate is subcritical, we obtain a phylogenetic tree consistent with an...
