Course detail

Probability and Statistics II

FSI-SP2CompulsoryBachelor's (1st cycle)Acad. year: 2016/2017Summer semester3. year of study5  credits

This course is concerned with the following topics: multidimensional normal distribution, linear regression model (estimates, tests of hypotheses, regression diagnostics), nonlinear regression model, introduction to ANOVA, categorial analysis, selected multivariate methods (correlation analysis). Students learn of the applicability of those methods and available software for computations.

Learning outcomes of the course unit

Students acquire needed knowledge from important parts of the probability theory and mathematical statistics, which will enable them to evaluate and develop stochastic models of technical phenomena and processes based on these methods and realize them on PC.

Mode of delivery

90 % face-to-face, 10 % distance learning

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Course-unit credit requirements: active participation in seminars, mastering the subject matter, passing both written exams and semester assignment acceptance. Preparing and defending a project. Examination (semester assignment (12 points) and written form of exam (88 points) consisting of two parts: a practical part (4 tasks related to: random vectors, conditional distribution, multivariate normal distribution, regression analysis, categorial data analysis); theoretical part (4 tasks related to basic notions, their properties, sense and practical use, and proofs of two theorems); evaluation: each task 0 to 18 points and each theoretical question 0 to 4 points; evaluation according to the total number of points (scoring 0 points for any theoretical part task means failing the exam): excellent (90 - 100 points), very good (80 - 89 points), good (70 - 79 points), satisfactory (60 - 69 points), sufficient (50 - 59 points), failed (0 - 49 points).
