1. Methods for handling model misspecification in pharmacometric model-based approaches for the analysis of longitudinal clinical trial data
Sammanfattning : Pharmacometrics model-based analyses proved to be increasingly useful in drug discovery and development. This usefulness was made evident by the formalisation of the model-integrated drug discovery and development framework (MID3). LÄS MER
2. Generalization under Model Mismatch and Distributed Learning
Sammanfattning : Machine learning models are typically configured by minimizing the training error over a given training dataset. On the other hand, the main objective is to obtain models that can generalize, i.e., perform well on data unseen during training. LÄS MER
3. Optimal Stopping and Model Robustness in Mathematical Finance
Sammanfattning : Optimal stopping and mathematical finance are intimately connected since the value of an American option is given as the solution to an optimal stopping problem. Such a problem can be viewed as a game in which we are trying to maximize an expected reward. LÄS MER
4. Some aspects of statistical inference in systems of equations
Sammanfattning : The objective of this thesis is to develop a strategy for statistical/econometric inferences applicable to systemwise testing of econometric models. A common deficiency in many applied econometric studies is the absence of statistical diagnostic testing. LÄS MER
5. Learning about the unobservable : The role of attitudes, measurement errors, norms and perceptions in user behaviour
Sammanfattning : Unobservable factors are important to understand user behaviour. Moreover, they contain information to help design services that willsolve today’s challenges. Yet, we have barely scratched the surface ofthe underlying mechanisms ruling user behaviour. LÄS MER
