[Gretl-users] Cointegration tests on many pairs of historic series

Dear Gretl users, I need your help for running the Johansen test automatically on (n) historic series, matched in pairs. Substantially, I have 30 historic series, and I must test the cointegration between all the possible pairs. Then, existing 435 possible pairs, I need an automatic procedure to make this great number of Johansen tests. Overall, I need a procedure that can run all possible cointegration tests on a number of pairs of historic series given by the binomial coefficient (combination), that in the specific case is n=30, k=2, then [30!/(2!*(30-2)!]=435 pairs, and 435 Johansen tests. Thank you for you help! Matteo Chiorboli
