1- open a quarterly/monthly series
2- select a variable and go to /Variable/Tramo analysis
3- remove the tickmark on "Standard automatic analysis" (if you leave
this tickmark all is ok)
4- you may leave the default on "Time series model plus seasonal
adjustment" (TRAMO+SEATS) or select "Time series model only" (TRAMO only)
Please have a look at "Transformations" tab, the option "automatic"
(with respect to log/no log transformation) is selected by default.
5- click on OK and gretl transfer the info to TRAMO/SEATS and run the
external program
The TRAMO/SEATS window output shows a list of the parameters received
from gretl. You will see the parameter LAM=1 (no logs) instead of LAM=-1
(automatic).
I have checked this on Windows 7 (gretl 1.9.9x) and Ubuntu Linux 14.04
(gretl from yesterday cvs)
