WebADF Test in Stata: Once again, I recommend you to show explicitly what are the NULL and ALTERNATIVE hypotheses of this test, and the regression equations you are going to run. Then, using the STATA, you have two ways to perform the test: using the dfuller command , or ; using OLS (but checking for significance in the Dickey-Fuller tables) WebAugmented Dickey-Fuller Test data: wn Dickey-Fuller = -4.8309, Lag order = 4, p-value = 0.01 alternative hypothesis: stationary. The null hypothesis is rejected. Try a Dickey-Fuller test. This is testing with a null hypothesis of AR(1) stationarity versus a null hypothesis with AR(4) stationarity when we used the default k.

WebDec 20, 2024 · The output window of STATA reflects on the Dickey-Fuller test results for variable ‘gdp_d1’. To examine the presence of stationarity, review two values; ‘Z(t)’ and Mackinnon p-value for ‘Z(t)’. Here it can be seen that the ‘Z(t)’ value is -7.073 which is a large negative number (as compared to ‘z(t)’ for ‘gdp’) and the p ...

Determining the stationarity of a time series is a key step before embarking on any analysis. The statistical properties of most estimators in time series rely on the data being (weakly) stationary.
