  1. 1. Neural Network Approaches To Survival Analysis

    Author : Jonas Kalderstam; Beräkningsbiologi och biologisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Survival Analysis; Artificial Neural Networks; Machine Learning; Genetic Algorithms; Evolutionary Algorithms; Fysicumarkivet:2015:Kalderstam;

    Abstract : 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). READ MORE

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

    Author : Szilard Nemes; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biostatistics; cancer; survival analysis; gemonics; DNA copy number aberrations; messenger RNA;

    Abstract : 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. READ MORE

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

    Author : Frank Eriksson; Chalmers tekniska högskola; Göteborgs universitet; Gothenburg University; []
    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. 4. On a journey for survival : everyday life during radiation therapy from the perspectives of women with breast cancer and their families

    Author : Annette Holst-Hansson; Malmö universitet; []
    Keywords : Breast cancer; Radiation therapy; Content analysis; Hermeneutic phenomenology; Thematic analysis;

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

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

    Author : Jenny Nykvist; Henry Ohlsson; Eva Mörk; David Blanchflower; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Self-employment; entrepreneurship; liquidity constraints; wealth; displacement; plant closure; survival; success; Economics; Nationalekonomi;

    Abstract : 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. READ MORE
