The alternative hypothesis is different depending on which version of the test is used, but is usually stationarity or trend-stationarity. It is an augmented version of the Dickey–Fuller test for a larger and ...

WebDickey-Fuller Tests • If a constant or trend belong in the equation we must also use D-F test stats that adjust for the impact on the distribution of the test statistic (* see problem set 3 where we included the drift/linear trend in the Augmented D-F test). • The D-F is generalized into the Augmented D-F test to accommodate the general WebThis means that we can simply calculate a t-statistic and compare it to the critical values of a Dickey-Fuller table. The Dickey-Fuller test is one of the simplest tests to determine if a time series has a unit root or not. The …

WebApr 11, 2013 · This tests the null hypothesis that Demand follows a unit root process. You usually reject the null when the p-value is less than or equal to a specified significance level, often 0.05 (5%), or 0.01 (1%) and even 0.1 (10%). Your approximate p-value is 0.2924, so you would fail to reject the null in all these cases, but that does not imply that the null …
