    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. Self-employment Entry and Survival Evidence from Sweden

    Detta är en avhandling från Uppsala : Nationalekonomiska institutionen

    Författare :Jenny Nykvist; Uppsala universitet.; [2008]

    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
