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

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

   Abstract : 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.

5. 3. Local Influence Analysis and Cross-over Studies

   Author : Chengcheng Hao; Tatjana von Rosen; Dietrich von Rosen; Thomas Holgersson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Delta-beta-based local influence; Explicit maximum likelihood estimate; Influential observation; Mixed linear model; Perturbation scheme; Statistical diagnostics; Statistics; statistik;

   Abstract : With a special reference to cross-over design models with random individual effects, the purpose of this dissertation is to develop new methodology to detect influential observations in the context of mixed linear models with explicit maximum likelihood estimators (MLEs).Case-weighted perturbation schemes within and between subjects in mixed models are constructed.

6. 4. Explicit Influence Analysis in Crossover Models

   Author : Chengcheng Hao; Tatjana von Rosen; Dietrich von Rosen; Tapio Nummi; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; explicit maximum likelihood estimate; generalised mixed linear model; influential observation; perturbation scheme; statistical diagnostics; Statistics; statistik;

   Abstract : This dissertation develops influence diagnostics for crossover models. Mixed linear models and generalised mixed linear models are utilised to investigate continuous and count data from crossover studies, respectively. READ MORE

7. 5. Corporate governance and corporate entrepreneurship : empirical studies on Swedish riding schools
