Aug 02, 2015 · Now see what the actual **test** statistic is: 10.134. That is less extreme than the conventional 5% value (and even the 10% value) because it is less negative than -2.639 (and even -1.605). Therefore, you do not reject the null hypothesis of **unit** **root** at any of the conventional significance levels. You data seems to be nonstationary..

I want to perform **unit** **root** **tests** (ADF, DFGLS, KPSS) on a group of variables, say X1, X2, X3, X4. Is it possible to write code in **Stata** to perform the **tests** in one go for all variables? I tried using foreach, but was unsuccessful. In a **Stata** do-file I tried: foreach var of varlist lic lac ldc lcc { dfuller 'var' }.
