Notes: The values in without parenthesis are the augmented dickey Fuller test-statistic values and the values in parentheses in columns 2nd and 3rd are Test-statistic critical values. Values in parentheses in column 4rth are order of stationarity *10% level of significance. **5% significance. ***1% level of significance. The values in parenthesis are representing standard errors.
