  1. 1. Bayesian networks: exact inference and applications in forensic statistics

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Ivar Simonsson; Göteborgs universitet.; Gothenburg University.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian networks; variable elimination algorithm; forensic statistics; relationship inference; mutation models;

    Abstract : Exact inference on Bayesian networks has been developed through sophisticated algorithms. One of which, the variable elimination algorithm, identifies smaller components of the network, called factors, on which local operations are performed. In principle this algorithm can be used on any Bayesian network. READ MORE

  2. 2. Bayesian Cluster Analysis Some Extensions to Non-standard Situations

    University dissertation from Stockholm : Statistiska institutionen

    Author : Jessica Franzén; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cluster analysis; Clustering; Classification; Mixture model; Gaussian; Bayesian inference; MCMC; Gibbs sampler; Deviant group; Longitudinal; Missing data; Multiple imputation; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik; statistik; Statistics;

    Abstract : The Bayesian approach to cluster analysis is presented. We assume that all data stem from a finite mixture model, where each component corresponds to one cluster and is given by a multivariate normal distribution with unknown mean and variance. READ MORE

  4. 4. On Bayesian graphical model determination

    University dissertation from Stockholm : Statistiska institutionen

    Author : Jukka Corander; Stockholms universitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian inference; Entropy; Exponential models; Graphical models; Logarithmic utility; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik; statistik; Statistics;

    Abstract : A graphical model specifies a graph representation of the independence structure of a multivariate distribution, where nodes represent variables and edges association between variables.This thesis introduces methodology for determination of graphical models for multivariate distributions within the exponential family.

  5. 5. Bayesian Modeling of Conditional Densities

    University dissertation from Stockholm : Department of Statistics, Stockholm University

    Author : Feng Li; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian inference; Density estimation; smooth mixtures; surface regression; copulas; Markov chain Monte Carlo; statistik; Statistics;

    Abstract : This thesis develops models and associated Bayesian inference methods for flexible univariate and multivariate conditional density estimation. The models are flexible in the sense that they can capture widely differing shapes of the data. The estimation methods are specifically designed to achieve flexibility while still avoiding overfitting. READ MORE
