[Gretl-users] Optimization

Hi, 1) Doing a adf 0 y --ct --verbose, there is a time coefficient on the output What is this time coefficient? 2) Does gretl allow doing regression with optimization of some condition? Have 6 data D1 to D6 Want to regress D1 against D2 to D6 Do a adf on the $yhat and have t value Want to have the coefficients of D2 to D6 MAXIMISING the t value Try seraching the manual on the 2) Claordina
