Sorry for my silly question :) I didn't know "$i" is only for strings. Now
my script is working just fine. Thanks Allin!

Why are you using two loops? Conceptually, there's only one:

loop foreach i Variables -q

 adf lag $i --c --test-down

 ADF[i,] = $test ~ $pvalue
endloop

You should use "$i" (and the like) _only_ when you need string
substitution (as in the adf command): otherwise use plain "i"
(as in matrix indexation) to get the numerical value.

Sorry for my silly question :) I didn't know "$i" is only for strings. Now
my script is working just fine. Thanks Allin!
