ECTS credit allocation (and other scores): 6.00 Basic information on ECTS credits allocation principles:
  • the annual hourly workload of the student’s work required to achieve the expected learning outcomes for a given stage is 1500-1800h, corresponding to 60 ECTS;
  • the student’s weekly hourly workload is 45 h;
  • 1 ECTS point corresponds to 25-30 hours of student work needed to achieve the assumed learning outcomes;
  • weekly student workload necessary to achieve the assumed learning outcomes allows to obtain 1.5 ECTS;
  • work required to pass the course, which has been assigned 3 ECTS, constitutes 10% of the semester student load.

Short description:

Master's level course.

The lecture gives theoretical basis for time series modelling. Participants will acquire theoretical knowledge about concepts and tools used in time series analysis and forecasting. The role of practical sections is to practise econometric analysis of time series: preparing the data, estimation and post estimation procedures, model verification and diagnostics, forecasts building and evaluation. Every topic discussed during the lecture will be illustrated with case study examples and exercises to be solved by students. R software will be used - its previous knowledge is not required.

Full description:

Learning outcomes:

Students will be able to identify features of time series and select best modeling method. They will know how to decompose time series into its components, identify, estimate and interpret models in univariate and multivariate time series framework (for macroeconomic and financial data), produce and evaluate forecasts and verify research hypotheses. In addition, students will know how to apply wide range of models, including modeling non-stationary time series and long-run relationships between economic variables.
