STAT 497 LECTURE NOTES 5

STAT 497 LECTURE NOTES 5. UNIT ROOT TESTS. UNIT ROOTS IN TIME SERIES MODELS. Shock is usually used to describe an unexpected change in a variable or in the value of the error terms at a particular time period. When we have a stationary system, effect of a shock will die out gradually.

Univariate Time Series

Univariate Time Series. Concerned with time series properties of single series. Denote y t to be observed value in period t Observations run from 1 to T Very likely that observations at different points in time are correlated as economic time series change only slowly. Stationarity.

CHAPTER 13

CHAPTER 13. STATIONARY AND NONSTATIONARY TIME SERIES. TIME SERIES. Most economic time series in level form are nonstationary . Such series often exhibit an upward or downward trends over a sustained period of time. But such a trend is often stochastic and not deterministic.
