  2. 1. Exact inference in Bayesian networks and applications in forensic statistics

    Author : Ivar Simonsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; forensic statistics; familial relationship inference; Bayesian networks; variable elimination; exact inference; mutation models;

    Abstract : 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. READ MORE

  4. 2. Bayesian networks: exact inference and applications in forensic statistics

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

    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

  5. 3. Bayesian Inference for Automotive Applications

    Author : Maryam Fatemi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE

  6. 4. Predictability in Equity Markets: Estimation and Inference

    Author : Tamás Kiss; Erik Hjalmarsson; Ádám Faragó; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Different Aspects of Inference for Spatio-Temporal Point Processes

    Author : Ottmar Cronie; Göteborgs universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Asymptotic normality; Consistency; Edge correction; Immigration-death process; Least squares estimation; Maximum likelihood estimation; Spatio-temporal marked point process; Transition probability.; Consistency;

    Abstract : This thesis deals with inference problems related to the Renshaw-Särkkä growth interaction model (RS-model). It is a continuous time spatio-temporal point process with time dependent interacting marks, in which the immigrationdeath process (a continuous time Markov chain) controls the arrivals of new marked points as well as their potential life-times.
