  3. 2. Nonparametric Functional Estimation under Order Restrictions

    Författare :Dragi Anevski; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; monotonicity; convexity; deconvolution; kernel smoothing; NPMLE; long range dependence; greatest convex minorant; mixing; Density estimation; limit distribution.; regression; Mathematics; Matematik;

    Sammanfattning : This thesis consists of three papers (Papers A-C) on problems in nonparametric functional estimation, in particular density and regression function estimation and deconvolution, under order assumptions. Pointwise limit distribution results are stated for the obtained estimators, which include isotonic regression estimates, nonparametric maximum likelihood estimates of monotone densities, estimates of convex regression and density functions and deconvolution estimates.

  4. 3. Order restricted inference over countable preordered sets. Statistical aspects of neutron detection

    Författare :Vladimir Pastukhov; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Constrained inference; Isotonic regression; Density estimation; Grenander estimator; Limit distribution; Neutron detection;

    Sammanfattning : This thesis consists of four papers. In the first paper, we study the isotonic regression estimator over a general countable preordered set. We obtain the limiting distribution of the estimator and study its properties. Also, it is shown that the isotonisation preserves the rate of convergence of the underlying estimator. LÄS MER

  5. 4. The relevance and assessment of limb muscle function in individuals with chronic obstructive pulmonary disease

    Författare :Erik Frykholm; André Nyberg; Ann Sörlin; Per Stål; Thomas Sandström; Lars Nyberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; COPD; lower and upper limb activities; quadriceps function; reliability; association; physiotherapy; fysioterapi;

    Sammanfattning : Chronic obstructive pulmonary disease (COPD) is a disease that is characterised by persistent respiratory symptoms and airflow limitation. Consequences beyond the airways and lungs are common, and include limb muscle dysfunction. LÄS MER

  7. 5. A multi-disciplinary approach to studying performance among high-level golfers : physiological and biomechanical aspects

    Författare :James Parker; Charlotte M. Olsson; Toni Arndt; Högskolan i Halmstad; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carry distance; clubhead speed; driver performance; golf kinematics; sports performance; strength training; isokinetic training;

    Sammanfattning : In competitive golf, the player’s ability to hit the ball a long distance affects the score in a positive way. Swing kinematics is considered an important factor in driver performance; one way of improving swing kinematics is through strength and power training. LÄS MER
