# Mathematical Statistics

In mathematical statistics the aim is to analyze data sets (samples) to gain insight on a broader entirety. Students of this course will be introduced to the basics behind the theory of mathematical statistics in a comprehensive introduction. Essential estimation and test methods are presented. These methods will also be implemented in modern software languages accompanied by the application examples which will give students a deeper understanding of the theory. Furthermore, the goal is to teach all fundamentals needed for more advanced statistical purposes such as in biostatistics, actuarial sciences and finance.
