[Gretl-devel] CRASH: panel-ADF in 1st differences

Hi all, I've just encountered a crash when calling the "--difference" option for the "adf" command in a panel-setting (no crash in a time-series setting, though). Here is a sample script: <hansl> set verbose off open grunfeld.gdt --quiet # in levels -> WORKS adf -1 invest --ct # 1st differences -> CRASH adf -1 invest --c --difference </hansl> This is with gretl-2026c from 2026-05-25 on my Ubuntu machine. Thanks in advance and best wishes, Artur
