HI, I AM USING GRETL FOR MAC (QUARTZ). WHEN I CONDUCT THE ADF TEST, THE TEST DOWN FOR LAG ORDER DOES NOT DISPLAY THE “MODIFIED” AIC AND BIC RATHER AIC AND BIC. THE RESULTS WHEN I COMPARE ARE DIFFERENT FOR MAC (WITHOUT “MODIFIED” AIC) THAN THE MODIFIED AIC THAT IS AVAILABLE WHEN USING GRETL FOR WINDOWS. I WOULD BE GRATEFUL IF YOU COULD SUGGEST A SOLUTION TO THIS CONFUSION. THANKS, DIPANKAR _______________________________________________
