Meeting students, Course goals, expected knowledge after completing the course, explain methods of evaluating the student’s performance
2
 
Introduction-examples of time series data- goals of time series analysis- measuring forecasting errors-choosing the appropriate method for forecasting- types of change in time series
3
 
Covariance function-autocorrelation function (importance – estimation)- form of the ACF for some cases (non-stationary series , oscillating series, seasonal series)- partial autocorrelation function- estimating the PACF
4
 
Time series operators (backshift operator, difference operator), using the difference operator for non-stationary series in the mean- variance stabilizing transformations-Box-Cox transformations
5
 
 
Stochastic time series models- meaning of linearity in regression models and in time series models-white noise process- stationarity of W.N. process- general linear process- invertibility formula- white noise formula- autoregressive processes (AR)- autoregressive process of order one (stationarity condition, ACF, PACF)
6
 
AR(2) (stationarity conditions, ACF, PACF)-  general AR(p)- moving average processes (MA)- MA(1) (invertibility condition, ACF, PACF)
7
 
MA(2) (invertibility condition, ACF, PACF)- general MA(q)- ARMA(p,q) models- ARMA(1,1) model (stationarity condition, invertibility condition ACF, PACF)- integrated ARIMA(p,d,q) models
Week 7 First  Midterm exam (date to be agreed upon with students)
8
 
Parameter estimation- moments method - estimating white noise variance- least squares method
9
 
Forecasting – minimum mean square error forecast- forecasting for AR(1), MA(1) , some results for the general ARMA(p,q), forecast error variance- constructing confidence limits for the forecasts-updating the forecasts
10
