st: levinlin

Hi Users
 
Hoping someone can help with the following problem:
When I use the levinlin command to dependent variable lnQ, I guet the bellow response ( independently of the number of lags):
 
levinlin lnQ, lag(0)
 
Levin-Lin-Chu test for lnQ        Deterministics chosen: constant
 no observations
 r(2000);
 
Thanks in advance.
N.K
