    Sammanfattning : 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. LÄS MER

    Sammanfattning : Methods other than averages from national tests, grades and levels of eligibility for higher education to evaluate the quality of education and school development are called for. In this dissertation is examined how a conscious effort to develop trustful relationships and mutual interaction among all actors in schools may contribute to increased well-being, community and strengthened learning processes for both students and teachers.

  5. 9. Identifying Influential Observations in Nonlinear Regression : a focus on parameter estimates and the score test

    Författare :Karin Stål; Tatjana von Rosen; Sune Karlsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Added parameter plot; differentiation approach; influential observation; nonlinear regression; score test; Statistics; statistik;

    Sammanfattning : This thesis contributes to influence analysis in nonlinear regression and in particular the detection of influential observations. The focus is on a regression model with a known mean function, which is nonlinear in its parameters and where the function is chosen according to the knowledge about the process generating the data.
