WebThe augmented Dickey Fuller (ADF) test for unit roots was conducted for all the time series used for the study. Table B1 shows the result of unit root tests using the ADF unit root test at the first difference level. The null hypothesis of nonstationarity was performed at the 1%, 5%, and 10% significance levels.
