  2. 1. Prostate cancer incidence, treatment and mortality : Empirical longitudinal register-based studies and methods for handling missing data

    Author : Marcus Westerberg; Rolf Larsson; Hans Garmo; Pär Stattin; Jimmy Olsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistics; mathematics; prostate cancer; missing data; survival analysis; longitudinal models; incidence; treatment; mortality; Mathematical Statistics; Matematisk statistik; Statistics; Statistik; Urologi; Urology; Epidemiologi; Epidemiology;

    Abstract : The diagnostic activity for prostate cancer has increased substantially in Sweden, primarily due to increased use of prostate-specific antigen (PSA) testing in asymptomatic men, and this has led to a large increase in diagnoses. There have also been changes in the diagnostic workup, guidelines, treatment strategies, and more effective treatments have been introduced in different phases of the disease. READ MORE

  4. 2. On the Application of the Bootstrap : Coefficient of Variation, Contingency Table, Information Theory and Ranked Set Sampling

    Author : Saeid Amiri; Silvelyn Zwanzig; Rolf Larsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bootstrap method; Categorical data; Coefficient of variation; Entropy; Exponential family; Monte Carlo investigation; Informational energy; Ranked set sampling; Variance-stabilization transformation; Statistics; Statistik;

    Abstract : This thesis deals with the bootstrap method. Three decades after the seminal paper by Bradly Efron, still the horizons of this method need more exploration. The research presented herein has stepped into different fields of statistics where the bootstrap method can be utilized as a fundamental statistical tool in almost any application. READ MORE

  5. 3. Empirical Bayes Methods for DNA Microarray Data
