  2. 1. On Estimation and Prediction in Linear Mixed Models : A new approach to studying equal BLUEs and BLUPs

    Author : Azadeh Chizarifard; Tatjana von Rosen; Katarzyna Filipiak; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Best linear unbiased estimator; Best linear unbiased predictor; Linear zero function; Matrix equations; statistik; Statistics;

    Abstract : Linear mixed models (LMMs) are widely used to analyze repeated, longitudinal, or clustered data in many disciplines, such as biology, medicine, psychology, sociology, economics, etc. One of the essential components of a linear mixed model is its covariance structure, i.e. READ MORE

  7. 5. Opportunity creation as a mixed embedding process : A study of immigrant entrepreneurs in Sweden

    Author : Quang V. D. Evansluong; Caroline Wigren-Kristoferson; Marcela Ramirez-Pasillas; Monder Ram; Jönköping University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; immigrant entrepreneurship; opportunity creation; entrepreneurial opportunity; social integration; Sweden; mixed embeddedness; mixed embedding; företagsekonomi; immigrant entrepreneurship; opportunity creation; entrepreneurial opportunity; Social integration; sweden; mixed embeddedness; mixed embedding;

    Abstract : Entrepreneurial opportunities are frequently noted and addressed in the literature of immigrant entrepreneurship; however, little is known about how these entrepreneurial opportunities come into existence and how immigrant entrepreneurs create such opportunities. The purpose of this thesis is to examine why and how immigrant entrepreneurs create entrepreneurial opportunities through embedding processes in the home country and the host country. READ MORE
