Course objectives
A classical course of techniques for linear modeling of univariate (preferably discrete-time) random processes. After the basic theoretical introductory concepts illustrated by numerous examples a lot of selected standard parametric and nonparametric methods are dealt with in detail, allowing one to decompose the time series into its basic components: the deterministic one (typically trend and significant harmonics) and the residual noise. In addition many pre- and postprocessing procedures are included assisting one to choose an appropriate model and verify its quality. Exercises to the lecture are located in a computer lab and use MATLAB computing environment allowing the students to get the basic practical skill. They can run demo scripts related to individual topics of the lectures as well as fit models to simulated and real data using a variety of universal procedures. The implemented algorithms are fully transparent to the students and yield unlimited opportunity for their creativity.
Syllabus
  • Random process: definition, examples of typical processes, consistent system of distribution functions, Kolmogorov theorem, gaussian process, moment characteristics (mean, autocovariance and autocorrelation function), strict and weak stationarity, white noise, ergodicity, special cases of stationary random processes, properties of the autocovariance and autocorrelation function, estimated autocovariance and autocorrelation function, the algebraic and statistical interpretation of this estimate.
  • Decomposition model in time series analysis: choice of the model and its identification, the Box-Cox and power transformation, common methods for estimation of the deterministic components comprising both parametric methods (polynomial regression, growth curves etc.) and nonparametric methods (digital filtration, exponential weighting, spline and kernel smoothing, wavelet shrinkage etc.), randomness tests.
  • Identification of the periodic components: the small trend method, moving average method, the simultaneous estimate of the trend and seasonal component using linear regression, discrete Fourier transform, periodogram, periodicity tests.
  • Note: Computer-aided exercises are supported by the system MATLAB.
