May I ask, what does it mean if you take the log difference of both the
dependent and independent variables in an OLS, and then rho and DW stat
don't even appear in the output? The White's test value is quite small...
if i swap dependent/independent, the rho and DW stat reappear... Thanks TMN

If some regular regression stats don't appear that sounds strange. Could
you please show the output (copy & paste the pure text)?

Ah! I didn't see the line about missing observations. Maybe that's it?
[Paste below]:
Model 14: OLS, using observations 1900-1990 (T = 70)

DW is incorrect in cross-section setting, that's why DW option for cross-sections is
blank. Try to change dataset structure

My first answer is out of topic: one can't obtain differences for cross-sections.
"No rho" sounds starange
For example, (denmark.gdt from gretl native data) open
/usr/local/share/gretl/data/misc/denmark.gdt ols LRM const LRY LRM(-1)
from results Schwarz criterion −204.8132 Hannan-Quinn −208.4789 rho
0.096379 Durbin's h 0.799432
DW is substituted by Durbin's h becase of LRM(-1) in the right side Supply data set
(best variant - name of a gretl data file) and commands
