Belyankina, Head of section, Insurance Control Department, Ministry of Finance;Dr. P. Vasina, Consultant CARANA Ltd.) The course aims to provide students with basic models and methods of econometric modeling of financial time series. Such kind of data is typical for economics, its analysis is of great practical interest and has some specifics. Econometric modeling of time series serves to draw out economical (natural) laws from empirical observations, to make forecasts, to interpret data and to verify the hypotheses correspondent to economic time series. The course considers in detail the major methods of econometric modeling of time series, in particular modeling by stochastic processes, modeling of stationary and non-stationary time series, the spectrum analysis of time series. The course studies different aspects of existing methods, their properties, adequacy, and application to forecasting. The necessary background is the basic knowledge of linear algebra, mathematical analysis, probability theory, and mathematical statistics. Course outline: The stochastic processes.
