Mar 09, · To model a time series with the Box-Jenkins approach, the series has to be stationary. A stationary time series means a time series without trend, one having a constant mean and variance over time, which makes it easy for predicting values. Testing for stationarity – We test for stationarity using the Augmented Dickey-Fuller unit root test. The p-value resulting from the ADF test has to be less than or 5% for a time series . R was a very important milestone for both graphing and time series analysis with the release of lattice (Deepayan Sarkar) and grid (Paul Murrell) and also the improvements in ts mentioned above., All of these are covered in Volume 2 of R News, June Stock prices and time series 3 distribution does not change when shifted in time. Let X t be a stochastic process with joint probability distribution F. X t is a stationary process when the joint probability of the time-shifted process is the same for any time shift.
