  2. 1. On Bicompositional Correlation

    Author : Jakob Bergman; Statistiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Joint correlation coefficient; Empirical confidence coefficient; Dirichlet distribution; Correlation; Composition; Compositional data; Random variate generation; Simplex;

    Abstract : A composition is a vector of positive components summing to a constant, usually taken to be 1. Hitherto the research on compositional correlation has mainly focused on the correlation between the components of composition. This thesis is concerned with modelling the correlation between two compositions. READ MORE

  4. 2. Distal radioulnar joint: arthroplasty and strength assessments

    Author : Peter Axelsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Distal Radioulnar joint arthroplasty; Forearm torque and lifting strength measurements; Normative data; Reliability; Validity; Responsiveness;

    Abstract : The growing interest in distal radioulnar (DRUJ) disorders underlines the need for further improved evaluations of treatment outcome. Load-bearing and optimising torque are important features of the DRUJ, but they are rarely measured when assessing DRUJ interventions. READ MORE

    Keywords : Arthritis; Bone loss; Interleukin- 1 beta; Pain; Plasma; Progression; Radiographic changes; Synovial fluid; Temporomandibular joint; Tumor Necrosis Factor alpha;

    Abstract : In patients with rheumatoid arthritis and other inflammatory joint diseases, radiographic changes of the TMJ are frequently observed. Common symptoms of TMJ involvement are pain at rest and on movement of the jaw. READ MORE

  7. 5. Contributions to the Theory of Measures of Association for Ordinal Variables

    Author : Joakim Ekström; Rolf Larsson; Albert Satorra; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; Statistik; Statistics; statistik;

    Abstract : In this thesis, we consider measures of association for ordinal variables from a theoretical perspective. In particular, we study the phi-coefficient, the tetrachoric correlation coefficient and the polychoric correlation coefficient. READ MORE
