Course Enrolment Limitations

The course is also offered to the students of the fields other than those the course is directly associated with.

fields of study / plans the course is directly associated with

Course objectives

The objective is to provide a deeper insight into statistical methods suitable for multivariate data analysis, provide theoretical tools for the selected methods, and teach how to apply them, using a computer. The subject also presents special mathematical methods applied in economics, the methods being an indispensable part of modern management. Students learn the methods in such a way that they are able to apply them in marketing, and they also learn to control production quality in all stages of a production process, i.e. in the pre-production, production and the post-production stage.
