   Sammanfattning : Background: Patient and staff descriptions of everyday life in psychiatric inpatient care are consistent, revealing a challenging environment with over-reliance on medication and, power imbalances. Patients and staff ask for the opportunity to develop relationships; however, the literature on nursing interventions targeting these issues is sparse. LÄS MER

3. 2. Machine Learning Survival Models : Performance and Explainability

   Sammanfattning : Survival analysis is an essential statistics and machine learning field in various critical applications like medical research and predictive maintenance. In these domains understanding models' predictions is paramount. LÄS MER

4. 3. Self-employment Entry and Survival : Evidence from Sweden

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

5. 4. Survival Estimation for Opportunistic Maintenance

   Författare :Johan Svensson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-stationary renewal process; non-homogeneous Poisson process; survival; optimal maintenance; discretization; points of support; crack growth; discretization;

   Sammanfattning : The problem of rational maintenance of aircraft engines is studied with respect to the influence of random events. Aircraft engines can be more economically maintained and resources can be saved if the maintenance process is improved. LÄS MER

7. 5. Multiple Time Scales and Longitudinal Measurements in Event History Analysis

   Författare :Danardono; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; Cox regression; multiple events; proportiona hazards; random effects; survival analysis; time-dependent covariates; time origin; Statistik; Statistics; Statistik; Statistics; statistik;

   Sammanfattning : A general time-to-event data analysis known as event history analysis is considered. The focus is on the analysis of time-to-event data using Cox's regression model when the time to the event may be measured from different origins giving several observable time scales and when longitudinal measurements are involved.
