  1. 1. BAYESIAN HIERARCHICAL LINEAR MODELS FOR DIFFERENTIAL PROTEIN EXPRESSION ANALYSIS

    Master-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Siri Voghera; [2023]
    Nyckelord :Bayesian hierarchical modeling; differential protein expression analysis; proteomics;

    Sammanfattning : It is evident that the study of proteins is crucial for a deeper understanding of how drug treatments affect the body. However, differential protein expression analysis, which can be described as the method of finding which proteins are affected by a treatment, faces some major challenges. LÄS MER

  3. 2. Inverse Uncertainty Quantification for Sounding Rocket Dispersion

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Tove Ågren; [2022]
    Nyckelord :Uncertainty quantification; Bayesian inference; Rocket dispersion; Neural networks; Markov Chain Monte Carlo.; Osäkerhetskvantifiering; Bayesiansk inferens; Raketspridning; Neurala nätverk; Markovkedje-Monte Carlo;

    Sammanfattning : Sounding rocket impact points are subject to dispersion due to uncertainties in simulation model parameters and perturbations of the rocket trajectory during flight. Estimating the area of dispersion assumes that associated model uncertainties and magnitude of perturbations have already been inferred. LÄS MER

  4. 3. Spatial Statistical Modeling of Insurance Risk

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Oskar Tufvesson; [2017]
    Nyckelord :Insurance; Spatial modeling; Geographical pricing; Bayesian hierarchical modeling; Integrated Nested Laplace Approximation; Mathematics and Statistics;

    Sammanfattning : The aim of this thesis is to provide a statistical method for assessing the relative insurance risk associated with the policyholders geographical location. Number of claims and claims cost are modeled separately, where the Poisson distribution is assumed for the former and the Gamma distribution is assumed for the latter. LÄS MER

  5. 4. Evolvering av Biologiskt Inspirerade Handelsalgoritmer

    Magister-uppsats, Högskolan i Borås/Institutionen Handels- och IT-högskolan

    Författare :Patrick Gabrielsson; [2012]
    Nyckelord :Memory; Algorithmic Trading; Hierarchical Temporal; Neural Networks; Machine Learning; Predictive Modeling; Classification; Evolutionary Computing; Genetic Algorithm; Optimization;

    Sammanfattning : One group of information systems that have attracted a lot of attention during the past decade are financial information systems, especially systems pertaining to financial markets and electronic trading. Delivering accurate and timely information to traders substantially increases their chances of making better trading decisions. LÄS MER
