Hi,
(with current gretl cvs) there is a minor problem when you define your
own bars/shading to be included in time series plots via a text file
with date pairs. If I try to switch from one such date definition file
to another and apply the changes, gretl shows a shading which isn't
defined in the files. Re-applying seems to solve this, so this isn't a
big problem, but still, maybe it's an easy fix.
cheers,

Could you provide an example, please? I've tried experimenting
with this and I can't provoke the problem.

will try -- later. Actually it also happens that several entries named
"other..." (re-translated from German) appear in the drop-down menu,
which is clearly redundant. Maybe that provides you with another piece
of evidence.

Yes, that's helpful. See if it's better now, in current CVS.

New subject: ols fcast omit problem
Hello,
I have noticed a problem, with fcast command, which appears in such
script:
<script>
open data2-3.gdt
smpl 1959 1990
model1 <- ols unemp const cpi infl wggr
fcast 1991 1995
omit --auto
fcast 1991 1995
</script>
Both fcast commands give equal forecast results (corresponding to
model1), during the script without saving model to icon works ok:
<script>
open data2-3.gdt
smpl 1959 1990
ols unemp const cpi infl wggr
fcast 1991 1995
omit --auto
fcast 1991 1995
</scritp>
This script gives different forecast results. First fcast is based on
model given by ols, second one is based on model after omitting
variables.
Best regards,
Pawel

This script gives different forecast results. First fcast is based on
model given by ols, second one is based on model after omitting
variables.
Since the --auto form of "omit" always results in replacement
of the original model (provided something is in fact omitted),
the correct result is that the second "fcast" differs from the
first.
But I find that this is what happens. I've tried your script
in both gretlcli and the gretl GUI, and even in the GUI with
the first form of the script (where "model1" is saved) I'm
getting different forecasts before and after the "omit --auto"
command. For example, the prediction for unemp in 1991 is 7.3
from the first model and 7.6 for the second, after omission
of infl and wggr.
The language in which gretl is running obviously shouldn't
make any difference, but I tried in Polish too and saw the
same thing.
So I'm puzzled.

can't give a definite ok for lack of proper testing, but it does seem to
be better now.
