2. 1. Multiple Time Scales and Longitudinal Measurements in Event History Analysis

   Author : Danardono; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; Cox regression; multiple events; proportiona hazards; random effects; survival analysis; time-dependent covariates; time origin; Statistik; Statistics; Statistik; Statistics; statistik;

   Abstract : A general time-to-event data analysis known as event history analysis is considered. The focus is on the analysis of time-to-event data using Cox's regression model when the time to the event may be measured from different origins giving several observable time scales and when longitudinal measurements are involved.

4. 2. Evaluation of Students' Attitudes Towards Vocational Education in Jordan

   Author : Ahmed Al-Sa'd; Malmö högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; attitudes; students attitudes; vocational education; psychometrics; scaling techniques; factor analysis; multiple regression; logistic regression; attitude behaviour relationship;

   Abstract : This doctoral dissertation consists of the empirical main study and the explorative study. The main goal of the empirical study has been to acquire knowledge about students’ attitudes towards vocational education in Jordan, and to explore the dimensionality of their attitudes as well.

5. 3. Group-Sparse Regression : With Applications in Spectral Analysis and Audio Signal Processing

   Author : Ted Kronvall; Statistical Signal Processing Group; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sparse regression; group-sparsity; statistical modeling; regularization; hyperparameter-selection; spectral analysis; audio signal processing; classification; localization; multi-pitch estimation; chroma; convex optimization; ADMM; cyclic coordinate descent; proximal gradient;

   Abstract : This doctorate thesis focuses on sparse regression, a statistical modeling tool for selecting valuable predictors in underdetermined linear models. By imposing different constraints on the structure of the variable vector in the regression problem, one obtains estimates which have sparse supports, i.e. READ MORE
