Course detail
Probability and Statistics II
FSI-SP2 Acad. year: 2024/2025 Winter semester
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, correlation analysis, basic methods of categorical analysis. Students learn about the applicability of those methods and available software for computations.

Rules for evaluation and completion of the course
Course-unit credit requirements: active participation in seminars, mastering the subject matter, passing all written exams, and semester assignment acceptance. Preparing and defending a project.
Examination: written form of the exam (70 points) and oral part (30 points): a practical written part (4 tasks related to random vectors, conditional distribution, multivariate normal distribution, regression analysis, correlation analysis, categorical data analysis); theoretical oral part (4 tasks related to basic notions, their properties, sense and practical use, and proofs of two theorems); evaluation according to the total number of points (scoring 0 points for any of 4 practical tasks or whole theoretical part means failing the exam): excellent (90 – 100 points and both proofs), very good (80 – 89 points and both proofs), good (70 – 79 points and one proof), satisfactory (60 – 69 points), sufficient (50 – 59 points), failed (0 – 49 points).
Participation in the exercise is mandatory and the teacher decides on the compensation for absences.
Aims
The course objective is to make students majoring in Mathematical Engineering acquainted with theoretical background of regression analysis and with real applications of regression methods in technical practice.
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 apply them on PC.
