| Course abstract | |
| The subject of the statistical and econometrical methods course is the definition and optimal decision making of the following social-economic process problems: forecast methods of probabilistic situation, perspective tasks definition, development goals definition and analysis. Master students study parametric and non-parametric data processing methods, basic principles of choosing parametric and non-parametric statistical methods. | |
| Learning outcomes and their assessment | |
| • Knowledge - is able to show the depth or extends knowledge and understanding about parametric and nonparametric data analysis methods (1st test, 1st home work, practical works); Known time series regression analysis. Define economic hypotheses that include the relevant parameters and provide a basis for research, where the estimated parameters are not inconsistent with the fundamental laws of economics. (2nd test, 2nd home work, practical works); is able to apply knowledge of economic research related to the cross discipline fields (1st un 2nd home work, practical works).
• Skills – is able to independently use the theory, methods and problem-solving skills to carry out research activities in the economic evaluation of process parameters, using economic theory or hypothesis formulation (1st un 2nd test, 1st un 2nd home work, practical works). Is able to forcefully explain and discuss the data acquisition, economic theory and forecasting model specification for the particular problem at study (home works). • Competence – is able to independently formulate and critically analyze the economic hypotheses in master thesis, to evaluate the forecast of economic processes and to interpret the results. |

| Requirements for awarding credit points | |
| Exam evaluation depends on the semester cumulative assessment: 1st test (40 points), 2nd test (40 points), theory (20 points). 10 points equal to 1 point of exam mark. Test works can be written only at specified time and once. | |
| Description of the organization and tasks of students’ independent work | |
| 1st home work: Nonparametric and parametric methods for two and more samples analysis. (Upload in e-system). 2nd home work: Time series (Upload in e-system). | |
| Criteria for Evaluating Learning Outcomes | |
| Exam evaluation depends on the semester cumulative assessment (80%) and the theory (20%). The theory examination will be during the session. Students who have a cumulative assessment of the study course less than 4 or wish to improve it (at least 4) hold the theory or examination. The exam includes practical part (80%) and theory (20%). | |
