  1. 1. Non-Gaussian Statistical Modelsand Their Applications

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Zhanyu Ma; KTH.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Statistical modeling plays an important role in various research areas. It provides away to connect the data with the statistics. Based on the statistical properties of theobserved data, an appropriate model can be chosen that leads to a promising practicalperformance. LÄS MER

  2. 2. Noise Convolution Models: Fluids in Stochastic Motion, Non-Gaussian Tempo-Spatial Fields, and a Notion of Tilting

    Detta är en avhandling från Mathematical Statistics, Centre for Mathematical Sciences, Lund University

    Författare :Jörg Wegener; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; generalized Laplace; shallow water equations; asymmetry; noise convolution models; tempo-spatial fields; non-Gaussian model;

    Sammanfattning : The primary topic of this thesis is a class of tempo-spatial models which are rather flexible in a distributional sense. They prove quite successful in modeling (temporal) dependence structures and go beyond the limitation of Gaussian models, thus allowing for heavy tails and skewness. LÄS MER

  3. 3. Statistical analysis of non-Gaussian environmental loads and responses

    Detta är en avhandling från Centre for Mathematical Sciences, Lund University

    Författare :Ulla E.B. Machado; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actuarial mathematics; programmering; aktuariematematik; Statistik; operationsanalys; Statistics; operations research; programming;

    Sammanfattning : The thesis deals mainly with offshore engineering related problems where the dominant source of uncertainty is related to the loading. Loads arise from environmental random processes; e.g. waves, currents and winds. LÄS MER

  4. 4. Spatial Mixture Models with Applications in Medical Imaging and Spatial Point Processes

    Detta är en avhandling från Gothenburg : Chalmers University of Technolog

    Författare :Anders Hildeman; Göteborgs universitet.; Gothenburg University.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Non-Gaussian; Bayesian level set inversion; Point processes; Substitute CT; Finite mixture models; Spatial statistics; Gaussian fields;

    Sammanfattning : Finite mixture models have proven to be a great tool for both modeling non-standard probability distributions and for classification problems (using the latent variable interpretation). In this thesis we are building spatial models by incorporating spatially dependent categorical latent random fields in a hierarchical manner similar to that of finite mixture models. LÄS MER
