[Gretl-users] Loops again...

Hello again... I've got one more question with respect to my previous e-mail.... I've got 32 variables for 16 objects (2 for each of them) and want to use such a pairs of variables [1;17], [2;18], [3;19], ..., [16;32] to make some tests and computations. Why the following script doesn't work? Script: loop for i=1..16 k=i+16 adf 2 $i $k --c --test-down kpss 2 $i $k --trend coint2 1 $i $k vecm 1 1 $i $k endloop Best wishes... Mariusz Szczecin (Poland)
