Learning objectives:
  The course objective is to make students familiar with principles of theory stochastic processes and models used for analysis of time series as well as with estimation algorithms of their parameters. At seminars students practically apply theoretical procedures on simulated or real data using the software MATLAB. Result is a project of analysis and prediction of real time series.
  The course provides the introduction to the theory of stochastic processes. The following topics are dealt with: Types and basic characteristics, covariation function, spectral density, stationarity, examples of typical processes, time series and evaluating, parametric and nonparametric methods, identification of periodical components, ARMA processes. Applications of methods for elaboration of project time series evaluation and prediction supported by the computational system MATLAB.
Knowledge and skills required for the course:
  Rudiments of the differential and integral calculus, probability theory and mathematical statistics.
Syllabus of lectures:
  1. Stochastic processes, trajectories, examples, classification of stochastic processes.
  2. Consistent system of distribution functions, strict and weak stationarity.
  3. Momentum characteristics: the mean value, autocorrelation and partial autocorrelation, spectral density.
