| Course contents : | 1. Modelisation using regression methods: decomposition into trend, seasonal component and perturbation. Detecting outlyers, forcasting. 2. Moving averages: properties and construction. Usual moving averages: arithmetic, Henderdon, Spencer,... 3. Exponential smoothing, Brown's methods, Holt&Winters methods. 4.Theory of stationary processes: stationarity, autocorrelation, partial autocorrelation, spectral analysis, ARMA, ARIMA and SARIMA processes. |
 |
| Course objective : | Learning to analyse a time series using exploratory and modelling methods. Estimating its trend and seasonal components. Building and fitting ARIMA models. Making prediction. Estimating and using the power spectrum. |
