  1. 1. Conceptualizing and Measuring Well-Being Using Statistical Semantics and Numerical Rating Scales

    Författare :Oscar Kjell; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Well-being; Latent semantic analysis; Statistical semantics; Satisfaction with life; Harmony in life; Välbefinnande; Harmoni i livet; Tillfredsställelse med livet; Statistisk semantik; Latent semantisk analys;

    Sammanfattning : How to define and measure individuals’ well-being is important, as this has an impact on both research and society at large. This thesis concerns how to define and measure the self-reported well-being of individuals, which involves both theorizing as well as developing and applying empirical and statistical methods in order to gain a better understanding of well-being.

    Sammanfattning : Microwave sensors can be used within medicine as they use non-ionizing radiation, are often low cost, and can be designed for a specific purpose. The application of microwave sensors for diagnostics and monitoring can be improved using appropriate data analysis. The multi-layered structure of the human body makes the measurements on people complex. LÄS MER

  4. 3. Scalable Bayesian spatial analysis with Gaussian Markov random fields
