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

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

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

    Författare :Ivar Simonsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; forensic statistics; familial relationship inference; Bayesian networks; variable elimination; exact inference; 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

  4. 3. Populations and Statistics in Forensic Genetics

    Författare :Andreas Tillmar; Bertil Lindblom; Gunilla Holmlund; Petter Mostad; Peter de Knijff; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : DNA has become a powerful forensic tool for solving cases such as linking a suspect to a crime scene, resolving biological relationship issues and identifying disaster victims. Traditionally, DNA investigations mainly involve two steps; the establishment of DNA profiles from biological samples and the interpreta-tion of the evidential weight given by theses DNA profiles.

  5. 4. Assesing performance of PCR analysis using Bayesian modelling

    Författare :Ronny Hedell; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bayesian; Hierarchical model; PCR; Low-template DNA; Bacillus anthracis; Sensitivity; Forensic science; Forensic science;

    Sammanfattning : Different analytical methods are available to analyse the DNA samples from crime scenes or to screen samples for the presence of some target bacterium. For this purpose a method known as Polymerase Chain Reaction (PCR) can often be used. LÄS MER

  7. 5. Bayesian inference for detection problems in biology

    Författare :Ronny Hedell; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PCR; Bayesian inference; Forensic DNA analysis; Syndromic surveillance; Bacillus anthracis; Markov chain Monte Carlo; Allele dropout; Bacillus anthracis;

    Sammanfattning : This thesis is about different kinds of detection problems in biology: detection of DNA sequences in crime scene samples, detection of harmful bacteria in feed and food stuff and detection of epidemical diseases in animal populations. In each case, biological data is produced or collected in order to determine which DNA sequences, bacteria types or diseases are present, if any. LÄS MER
