COURSE AIMS AND OBJECTIVES:
The course objective is to introduce students to the fundamental concepts and results of time series analysis. Students will be introduced to classical and modern methods in modeling of real-life time series.

COURSE DESCRIPTION AND SYLLABUS:
1. Introduction (2 weeks) Examples of time series. Trend and seasonality. Autocorrelation function. Multivariate normal distribution.
2. Stationary sequences (5 weeks) Strong and week stationarity. Linear processes. ARMA models. Causality and invertibility of ARMA processes. MA(\infty) processes. Partial autocorrelation function. Estimation of autocorrelation function and other parameters. Forecasting stationary time series. Modeling and forecasting for ARMA processes. Asymptotic behavior of the sample mean and the autocorrelation function. Parameter estimation for ARMA processes.
3. Spectral analysis (2 weeks) Spectral density. Periodogram. Spectral density of ARMA processes. Herglotz theorem.
4. Nonstationary and nonlinear time series models (3 weeks) ARIMA and SARIMA models. Nonlinear models. ARCH and GARCH models. Chaotic deterministic time series models.
5. Statistics for stationary process (3 weeks) Asymptotic results for stationary time series. Estimating trend and seasonality. Nonparametric methods.
