  2. 21. Characterisation and Some Statistical Aspects of Univariate and Multivariate Generalised Pareto Distributions

    Author : Nader Tajvidi; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; generalised Pareto distribution; multivariate extreme value theory; multivariate Pareto distribution; small sample properties; Bartlett s correction; maximum likelihood; statistical computations; simulation AMS 1991 subject classification: 62F11; 62E20; 60F17; 65U05; 62E20;

    Abstract : Extreme value theory is about the distributions of very large or very small values in a time series or stochastic process. This has numerous applications connected with environmental science, civil engineering, materials science and insurance. READ MORE

  4. 22. A strategy for ranking environmentally occuring chemicals

    Author : Lennart Eriksson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QSAR; hazard ranking; statistical design; multivariate modelling; halogenated aliphatics; PCA; PLS;

    Abstract : A systematic methodology for quantitative structure-activity relationship (QSAR) development in environmental toxicology is provided. The methodology is summarized in a strategy with six sequential steps. READ MORE

    Author : Anders Danielsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mass spectrometry; gas chromatography; design of experiments; Metabolomics; chemometrics; diabetes; metabolism; multivariate analysis;

    Abstract : Metabolomics is a rapidly growing research field. It aims for quantification of all the metabolites in a biological sample such as plasma, saliva, cerebrospinal fluid or cells. READ MORE

  6. 24. Practical application of machine learning for analyses of biological matrices and environmental phenomena

    Author : Alexandra Walsh; Göteborgs universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Machine learning; Surface enhanced Raman spectroscopy; Acute lymphatic leukaemia; Volatile halogenated organic carbons; Marine algae; Doxorubicin; Principal component analysis; Multivariate statistics; Design of experiments; Waterlogged archaelogical wood; Transposed orthogonal partial least squares;

    Abstract : This thesis presents research aimed at forwarding an understanding of machine learning methods as a method of studying complex matrices and environmental phenomena. A number of machine learning methods in the form of linear projection algorithms and statistical experimental designs were applied for qualitative analysis of different matrices. READ MORE

  7. 25. Competitive performance prediction of elite alpine skiers

    Author : Robert Nilsson; Christer B. Malm; Apostolos Theos; Ann-Sofie Lindberg; Richard A. Ferguson; Örjan Ekblom; Umeå universitet; []
