  1. 1. Motivational Profiles and Their Relation to Coaching Behaviours and Dropout in Swedish Female Ice Hockey : A Latent Profile Analysis

    Kandidat-uppsats,

    Författare :John Groth; [2023]
    Nyckelord :Female ice hockey; Motivational profile; Coaching behaviour; Dropout; Person-centered; Damishockey; Motivationsprofil; Tränarbeteende; Avhopp; Personcentrerad;

    Sammanfattning : Purpose: The purpose of the present study was to use a person-centered approach to identify latent motivational profiles among female ice hockey players in Sweden, and examine how identified profiles relate to coaching behaviours and dropout. Methods: Swedish female ice hockey players (N = 140; Mage = 21.66, SD= 7. LÄS MER

  3. 2. Dimensionality Reduction in High-Dimensional Profile Analysis Using Scores

    Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Jonathan Vikbladh; [2022]
    Nyckelord :High-dimensional data; Hypothesis testing; LR test; Linear scores; Multivariate analysis; Profile analysis; Spherical distributions;

    Sammanfattning : Profile analysis is a multivariate statistical method for comparing the mean vectors for different groups. It consists of three tests, they are the tests for parallelism, level and flatness. The results from each test give information about the behaviour of the groups and the variables in the groups.

  4. 3. Assessment of Modern Statistical Modelling Methods for the Association of High-Energy Neutrinos to Astrophysical Sources

    Master-uppsats, KTH/Matematisk statistik

    Författare :Valentin Minoz; [2021]
    Nyckelord :Statistics; Astrophysics; Neutrino sources; Mixture models; Monte Carlo methods; Maximum likelihood estimation; Statistik; Astrofysik; Neutrinokällor; Blandningsmodeller; Monte Carlo-metoder; Maximum likelihood-metoden;

    Sammanfattning : The search for the sources of astrophysical neutrinos is a central open question in particle astrophysics. Thanks to substantial experimental efforts, we now have large-scale neutrino detectors in the oceans and polar ice. LÄS MER

  5. 4. The spatial distribution of dark matter in the Universe

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Tamina Lund; [2020]
    Nyckelord :dark matter halos; NFW profile; curve fitting; Bayesian inference; least Squares; data uncertainties; Physics and Astronomy;

    Sammanfattning : It was previously found that the density profile of dark matter halos is well-fit by a universal, smooth function over a vast range of masses and redshifts, named the Navarro-Frenk-White (NFW) profile after its discoverers. Despite its impressive goodness of fit, the NFW model remains an approximation of the density profile of realistic halos. LÄS MER

  7. 5. An Extreme Value Approach to Modeling Risk of Extreme Rainfall in Bangladesh

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Emmy Andersson; Evelina Nilsson; [2018]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The extreme value theory has been applied on daily rainfall in the five most exposed areas of Bangladesh between the years 1980-2016 in order to esti- mate extreme rainfalls for the next 10, 50 and 100 years. These types of computations are necessary for optimising planning and preparations for ex- treme future rainfalls which can lead to minimising property damage and ultimately saving lives. LÄS MER
