  1. 1. Neural Network Approaches To Survival Analysis

    Detta är en avhandling från Department of Astronomy and Theoretical Physics, Lund University

    Författare :Jonas Kalderstam; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Survival Analysis; Artificial Neural Networks; Machine Learning; Genetic Algorithms; Evolutionary Algorithms; Fysicumarkivet:2015:Kalderstam;

    Sammanfattning : Predicting the probable survival for a patient can be very challenging for many diseases. In many forms of cancer, the choice of treatment can be directly impacted by the estimated risk for the patient. This thesis explores different methods to predict the patient's survival chances using artificial neural networks (ANN). LÄS MER

  2. 2. Integrative genomic and survival analysis of breast tumors

    Detta är en avhandling från Göteborg : University of Gothenburg

    Sammanfattning : With the continued accumulation of genomic data at ever increasing resolution the challenge ahead lies in reading out meaningful clinical/biological information form the data that can contribute to a better understanding of the cancerous process. The need for novel approaches, new statistical methods is therefore strong. LÄS MER

  3. 3. Correlated random effects models for clustered survival data

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Frank Eriksson; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Survival analysis; frailty model; competing risks; random effects; case-cohort; routine register; semiparametric; competing risks; case-cohort; semiparametric; Survival analysis; random effects; routine register; frailty model;

    Sammanfattning : 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. LÄS MER

  4. 4. On a journey for survival everyday life during radiation therapy from the perspectives of women with breast cancer and their families

    Detta är en avhandling från Malmö universitet, Fakulteten för hälsa och samhälle

    Författare :Annette Holst-Hansson; [2018]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; Radiation therapy; Content analysis; Hermeneutic phenomenology; Thematic analysis;

    Sammanfattning : This thesis focuses on women diagnosed with breast cancer and their family members. Since a breast cancer diagnosis and its subsequent treatment are a strenuous experience not only for the woman afflicted but also for her family members, this thesis aimed to explore the experiences of everyday life during radiation therapy from the perspectives of the woman with breast cancer and her family, as well as exploring families’ experiences of participating in short family health conversations (SFamHC).

  5. 5. Self-employment Entry and Survival Evidence from Sweden

    Detta är en avhandling från Uppsala : Nationalekonomiska institutionen

    Författare :Jenny Nykvist; Henry Ohlsson; Eva Mörk; David Blanchflower; [2008]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Self-employment; entrepreneurship; liquidity constraints; wealth; displacement; plant closure; survival; success; SOCIAL SCIENCES Business and economics Economics; SAMHÄLLSVETENSKAP Ekonomi Nationalekonomi;

    Sammanfattning : Essay 1: Hurst and Lusardi (2004) use higher-order polynomials in wealth in estimating the relationship with entrepreneurship. They find evidence conflicting with the existence of extensive liquidity constraints in the United States. In this paper, their approach is replicated on Swedish data. LÄS MER
