Uhm, funny. I can't reproduce this. This is what I just tried (after downloading the dataset form sourceforge and storing the gdt file into a temporary dir): <hansl> set verbose off open /tmp/mroz.gdt --quiet series orig_order = time scalar check = ( min(diff(wage)) >= 0 ) && ( min(diff(lwage)) >= 0 ) printf "check: %d (unsorted: should be 0)\n", check dataset sortby wage scalar check = ( min(diff(wage)) >= 0 ) && ( min(diff(lwage)) >= 0 ) printf "check: %d (sorted by wage: should be 1)\n", check dataset sortby lwage scalar check = ( min(diff(wage)) >= 0 ) && ( min(diff(lwage)) >= 0 ) printf "check: %d (sorted by lwage: should be 1)\n", check dataset sortby orig_order scalar check = ( min(diff(wage)) >= 0 ) && ( min(diff(lwage)) >= 0 ) printf "check: %d (back to original: should be 0)\n", check </hansl> Could you please try this script?
