    Sammanfattning : The estimation of latent variable models with ordinal and continuous, or ranking variables is the research focus of this thesis. The existing estimation methods are discussed and a composite likelihood approach is developed. LÄS MER

  5. 19. Fluxes of Sensible and Latent Heat and Carbon Dioxide in the Marine Atmospheric Boundary Layer

    Författare :Erik Sahlée; Ann-Sofi Smedman; Anna Rutgersson; Sören Larsen; Uppsala universitet; []

    Sammanfattning : Oceans cover about 70% of the earth’s surface. They are the largest source of the atmospheric water vapour and act as enormous heat reservoirs. Thus in order to predict the future weather and climate it is of great importance to understand the processes governing the exchange of water vapour and heat between the ocean and atmosphere.

  7. 20. 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.
