  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. Predictability in Equity Markets: Estimation and Inference

    Detta är en avhandling från Göteborgs universitet

    Författare :Tamás Kiss; Göteborgs universitet.; Gothenburg University.; [2019]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Non-stationary regressor Persistence Adjustment Predictive Regressions Predictive System Present-value relationship Return Predictability Stock-return Predictability; Non-stationary regressor; Persistence Adjustment; Predictive Regressions; Predictive System; Present-value relationship; Return Predictability; Stock-return Predictability;

    Sammanfattning : The thesis consists of three chapters dealing with predictability in equity markets. The first chapter analyses predictive regressions in a predictive system framework, where the predictor is an imperfect proxy for the expected returns. LÄS MER

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

    Detta är en avhandling från Göteborg : Chalmers University of Technology

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

    Sammanfattning : 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. LÄS MER

  4. 4. Exact inference in Bayesian networks and applications in forensic statistics

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Ivar Simonsson; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; familial relationship inference; Bayesian networks; exact inference; forensic statistics; variable elimination; mutation models;

    Sammanfattning : Bayesian networks (BNs) are commonly used when describing and analyzing relationships between interacting variables. Approximate methods for performing calculations on BNs are widely used and well developed. LÄS MER

  5. 5. Partial and General Equilibrium Effects of Unemployment Insurance : Identification, Estimation and Inference

    Detta är en avhandling från Uppsala : Department of Economics, Uppsala University

    Författare :Mathias von Buxhoeveden; Björn Öckert; Johan Vikström; Rafael Lalive; [2019]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Labor Economics; Unemployment Insurance; Wage Level and Structure; Job Search; Duration Analysis; Econometric and Statistical Methods; Selection Models; Economics; Nationalekonomi;

    Sammanfattning : Essay I: Wage setting models typically posit a tight relationship between the generosity of unemployment insurance (UI) and equilibrium wages. This paper estimates the effect of UI on workers’ wages. LÄS MER
