  1. 1. Bayesian Phylogenetic Inference Estimating Diversification Rates from Reconstructed Phylogenies

    Detta är en avhandling från Stockholm : Department of Mathematics, Stockholm University

    Författare :Sebastian Höhna; Stockholms universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Phylogenetics; Bayesian inference; Graphical Models; Birth-Death Process; Diversification; matematisk statistik; Mathematical Statistics;

    Sammanfattning : Phylogenetics is the study of the evolutionary relationship between species. Inference of phylogeny relies heavily on statistical models that have been extended and refined tremendously over the past years into very complex hierarchical models. LÄS MER

  2. 2. Percolation: Inference and Applications in Hydrology

    Detta är en avhandling från Stockholm : Department of Mathematics, Stockholm University

    Författare :Oscar Hammar; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; percolation; inference; consistency; Markov chain Monte Carlo; hydrology;

    Sammanfattning : Percolation theory is a branch of probability theory describing connectedness in a stochastic network. The connectedness of a percolation process is governed by a few, typically one or two, parameters. LÄS MER

  3. 3. Learning of probabilistic inference tasks effects of uncertainty and function form

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Håkan Alm; Umeå universitet.; [1982]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inference; learning; cognition; Teknisk psykologi; Engineering Psychology;

    Sammanfattning : This thesis is concerned with the problem of how people learn to use uncer­tain information for making judgments. The general framework for the thesis is Social Judgment Theory (SJT). First the S3T paradigm, and some research conducted within the paradigm, is briefly described, and a series of four empirical studies is summarized. LÄS MER

  4. 4. Inference in a Partially Observed Percolation Process

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Oscar Hammar; Göteborgs universitet.; Gothenburg University.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Percolation; Bayesian inference; frequentistic inference; consistency; Markov chain Monte Carlo; Monte Carlo Expectation Maximization;

    Sammanfattning : In this licentiate thesis, inference in a partially oberved percolation process living on a graph, is considered.Each edge of the graph is declared open with probability $\theta$ and closed with probability $1-\theta$ independently of the states of all other edges. LÄS MER

  5. 5. Bayesian Phylogenetic Inference

    Detta är en avhandling från Stockholm University

    Författare :Sebastian Höhna; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis we consider two very different topics in Bayesian phylogenetic inference. The first paper, "Inferring speciation and extinction rates under different sampling schemes" by Sebastian Höhna, Tanja Stadler, Fredrik Ronquist and Tom Britton, focuses on estimating the rates of speciation and extinction of species when only a subsample of the present day species is available.
