What does adfuller test do?
ADF (Augmented Dickey-Fuller) test is a statistical significance test which means the test will give results in hypothesis tests with null and alternative hypotheses. As a result, we will have a p-value from which we will need to make inferences about the time series, whether it is stationary or not.
What is Adfuller in Python?
The adfuller function returns a tuple of statistics from the ADF test such as the Test Statistic, P-Value, Number of Lags Used, Number of Observations used for the ADF regression and a dictionary of Critical Values.
What is the difference between Dickey-Fuller test and augmented Dickey Fuller test?
The augmented Dickey-Fuller test is an extension of the standard Dickey-Fuller test, which also checks for both stationarity and non-stationarity in the time series. The main difference from the Dickey Fuller Test is that the Augmented Dickey Fuller test can also be applied on a large sized set of time series models.
