1. Bilinear Regression and Second Order Calibration
Abstract : We consider calibration of second-order (or "hyphenated") instruments for chemical analysis. Many such instruments generate bilinear two-way (matrix) type data for each specimen. The bilinear regression model is to be estimated from a number of specimens of known composition. READ MORE

2. Multivariate spectroscopic methods for the analysis of solutions
Abstract : In this thesis some multivariate spectroscopic methods for the analysis of solutions are proposed. Spectroscopy and multivariate data analysis form a powerful combination for obtaining both quantitative and qualitative information and it is shown how spectroscopic techniques in combination with chemometric data evaluation can be used to obtain rapid, simple and efficient analytical methods.

3. A two-step regression method with connections to partial least squares and the growth curve model
Abstract : Prediction of a continuous response variable from background data is considered. The independent prediction variable data may have a collinear structure and comprise group effects. A new two-step regression method inspired by PLS (partial least squares regression) is proposed. READ MORE

4. Conjoint analysis as a tool for communication and corporate environmental decision-making
Abstract : Conjoint analysis has been used extensively in marketing, transportation and healthcare for the past 50 years. Since the mid-1990s, it has also been applied to an increasing number of environmental issues. In this thesis, conjoint analysis is applied to environmental objectives of the Swedish steel industry.

5. Statistical advancements in analyzing accelerometer-measured physical activity intensity
Abstract : Physical activity (PA) is widely recognized as an important factor in preventing and treating cardiometabolic diseases and reducing mortality. Yet, the health implications of specific PA intensities and the intricate role of fitness in the relationship between PA and health remain less clear. READ MORE
