  3. 2. Some Investigations into the Class of Exponential Power Distributions

    Författare :Lukas Arnroth; M. Rauf Ahmad; Patrik Andersson; Matúš Maciak; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Exponential power distribution; Skewed exponential power distribution; linear mixed models; score test; Lp-quantiles; quantile regression; posterior convergence rate; Statistics; Statistik;

    Sammanfattning : In this thesis, methods are developed relating to the exponential power class of distributions.Paper I considers Bayesian linear mixed models where the usual normality assumption is replaced by the multivariate exponential power distribution. Particular focus lies on Bayesian testing of the fixed effects. LÄS MER

  5. 4. Intermittent Claudication : Prevalence and metabolic risk factors

    Författare :Jørgen Mølgaard; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The prevalence of intermittent claudication (IC) in middle-aged men (45-69 years old) and metabolic risk factors for this disease was studied in a Swedish community. All 15 253 middle-aged male residents in Linköping community, were screened for symptoms of IC using a postal questionnaire, which included detailed questions about smoking habits and presence of hypertension and diabetes mellitus.
