Objectives and competences

Analysing and interpreting data is an essential part of the work of a financial mathematician. The course presents statistical concepts and statistical models most commonly used in statistical practice

Intended learning outcomes

Introduction of statistical concepts sufficient for independent study and the ability to present and analyze data with more advanced statistical models.

Learning and teaching methods

Lectures, problem sessions, seminar assignment.

Assessment

2 midterms or written exam, oral exam.
Seminar assignment.
grading: 5 (fail), 6-10 (pass) (according to the Statute of UL)
