  1. 1. 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

  2. 2. 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

  3. 3. 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

  4. 4. Bayesian Inference for Automotive Applications

    Detta är en avhandling från Göteborgs universitet

    Författare :Maryam Fatemi; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Environment perception is an important aspect of modern automated systems. The perception consists of fusing information from different sensors to estimate variables which provide a description of the scene. LÄS MER

  5. 5. Searching for causal effects of road traffic safety interventions applications of the interrupted time series design

    Detta är en avhandling från Karlstad : Karlstad University Press

    Författare :Carl Bonander; Karlstads universitet.; Karlstads universitet.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Causal inference; Repeated measures; Methodology; Econometrics; Injury Epidemiology; Vulnerable Road Users; Time series analysis; Risk and Environmental Studies; Risk- och Miljöstudier;

    Sammanfattning : Traffic-related injuries represent a global public health problem, and contribute largely to mortality and years lived with disability worldwide. Over the course of the last decades, improvements to road traffic safety and injury surveillance systems have resulted in a shift in focus from the prevention of motor vehicle accidents to the control of injury events involving vulnerable road users (VRUs), such as cyclists and moped riders.
