  2. 1. Correlated random effects models for clustered survival data

    Author : Frank Eriksson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; competing risks; case-cohort; semiparametric; Survival analysis; random effects; routine register; frailty model; Survival analysis; frailty model; competing risks; random effects; case-cohort; routine register; semiparametric;

    Abstract : Frailty models are frequently used to analyse clustered survival data in medical contexts. The frailties, or random effects, are used to model the association between individual survival times within clusters. READ MORE

  4. 2. Essays on Immigrants' Economic Integration

    Author : Kerem Tezic; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Second-generation immigrants; educational attainments; early labour-market experiences; competing-risks; graduate employment; calibration; first-generation immigrants; sample-selection in panel data; random effects.;

    Abstract : This thesis consists of five papers, related to each other in terms of study-sample, study-subject or methods used. The first paper is concerned with second-generation immigrants' educational attainments, using the Longitudinal Individual Data-set (LINDA), which gave us the possibility to examine changes over time, from ages 16-17 to 21-22 and to compare second-generation immigrants with a randomly-chosen matched control-group of native Swedes.

  5. 3. Development and application of competing risks and multi-state models in cancer epidemiology

    Author : Nikolaos Skourlis; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Competing risks and multi-state models allow us to study complex disease settings and answer composite research questions and should be used more widely in epidemiology. This thesis aims to explore the competing risks and multi-state models areas using flexible parametric survival models (FPSMs), studying several aspects, such as the choice of timescale, choice of multi-state structure, sharing information across transitions by imposing restrictions in the estimation of the parameters, as well as communicating the results of such models to a wider audience and evaluating the use of recurrent multi-state structures in the area of recurrent events when a terminal event is present.

  6. 4. Prostate Cancer; Metabolic Risk Factors, Drug Utilisation, Adverse Drug Reactions

    Author : Birgitta Grundmark; Lars Holmberg; Björn Zethelius; Gunnar Engström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; Epidemiology; Pharmacoepidemiology; Metabolic Syndrome; Selenium; Smoking; hOGG1; MnSOD; Competing Risk; Adherence; Persistance; Medical Possession Ratio; MPR; Signal Detection; PRR; proportional reporting ratio; ULSAM; PcBaSE; EudraVigilance; SPDR; Swedish Prescribe Drug Registry; NPCR; National Prostate Cancer Registry; SDR; Signal; disproportionality analysis; PRR-TA; EudraVigilance; Epidemiology; Epidemiologi; Kirurgi; särskilt urologi; Urology; Oncology; Onkologi; Geriatrics; Geriatrik;

    Abstract : Increased possibilities during the last decades for early detection of prostate cancer have sparked research on preventable or treatable risk factors and on improvements in therapy. Treatments of the disease still entail significant side effects potentially affecting men during the rest of their lives. READ MORE

  7. 5. Holistic approach in engineering design - controlling risks from accidental hazards in bridge design

    Author : Ivar Björnsson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design; codes; accidental; extreme; bridges; holistic; approach; robustness; risk; reliability; uncertainty;

    Abstract : Engineering design, in concise terms, is what engineers do using what they know. It is the underlying decision making activity that determines what is to be built and how it should be built. An ever present requirement in engineering design is that the structure should be safe.
