WebMay 25, 2024 · Example: Augmented Dickey-Fuller Test in Python Suppose we have the following time series data in Python: data = [3, 4, 4, 5, 6, 7, 6, 6, 7, 8, 9, 12, 10] Before we perform an augmented Dickey-Fuller test on the data, we can create a quick plot to visualize the data: import matplotlib.pyplot as plt plt.plot(data) In statistics, an augmented Dickey–Fuller test (ADF) tests the null hypothesis that a unit root is present in a time series sample. The alternative hypothesis is different depending on which version of the test is used, but is usually stationarity or trend-stationarity.

WebYou can access the DF Test tables given by Hamilton(1994) by clicking HERE. Here the null hypothesis is the presence of unit root. Thus, the augmented Dickey-Fuller statistic is -1.678, and lies inside the acceptance region at 1%, 5%, and 10%, as you can see form the tables. Therefore, we cannot reject the presence of unit root. WebMany statistical models require the series to be stationary to make effective and precise predictions.
