Background.. Stock proce analysis is very popular and important in financial study and time series is widely used to implement this topic. The data we use in this report is the daily stock price of ARM Holdings plc (ARM) from April 18th of to March 10th of . 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 . 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.
