Acknowledgement
First and foremost, I want to thank my supervisor Prof. Dr. Peter Bühlmann for the
excellent guidance and for introducing me with this fascinating topic. The interest he
demonstrated for my work has been a great source of motivation.
I want to express my gratitude to Prof. Dr. Sara Van de Geer of the Seminar for Statistics
and to Dr. Michel Baes of the Insitute for Operational Research for taking the time to
answer my questions. Also, I thank David Lamparter for many interesting discussions on
the Lasso.
Finally, writing this thesis would not have been possible without the friendly atmosphere
at the Seminar for Statistics. I would like to thank all staff members and the assistants for
helping me with mathematical or editing issues. To Sarah Gerster and Jürg Schelldorfer,
a huge thanks for the hospitality in the office.
