session error
by Summers, Peter
Hi folks,
I created a session file yesterday that included some graphs that I'd been editing. Now though, I can't re-open the session. Gretl says "xmlParseFile failed on .graphs of components\session.xml", and I can open other sessions with no problem. So I'm guessing this has to do with the edited plot commands? I've attached a copy if that helps.
TIA!

VAR Forecast
by Henrique Andrade
Dear Gretl Community,
I'm trying to perform forecasts using a VAR model. Please take a look
at the following script:
<script>
open australia.gdt
"VAR 1" <- var 1 E PAU PUS
fcast 1991:2 1991:4 --out-of-sample
matrix Previsao = $fcast
matrix ErroPadrao = $fcerr
</script>
The VAR estimation goes just fine, but the forecasting exercise gives
me this error warning:
<output>
? fcast 1991:2 1991:4 --out-of-sample
Data error
Error executing script: halting
> fcast 1991:2 1991:4 --out-of-sample
</output>
What I doing wrong?
Best,
--

Thanks for the report, That's now fixed.

True enough; now fixed.

Ok, I'll defer to you on that.

Can the results of forecasts be saved?
by Vivien Lee
Hello,
I'm new to gretl. So please bear with me.
I ran an ARIMA (2,1) model and then did an out-of-sample forecast. Original sample is set to use the first 1000 observations and the forecast is on observations 1001 to 1050. I want to save the predicted y values and then plot it along with the actual and fitted values and the unconditional mean. I can't seem to find any command to save the predicted values. Even if I can add the predicted values to the data set, I'm not sure how to include the unconditional mean on the graph.
Thank you in advance for your help,

Hmm, there were no visible errors on building the distribution
files -- maybe the upload went wrong somehow? I've now done a
new upload.

Probably the x12a "err" file actually said nothing but we got the
mistaken impression that it had some content. (x12a always
produces such a file, containing some "boilerplate" and blank
lines, if nothing else.) I've now adjusted the relevant test, so
hopefully you shouldn't get false positives. (CVS and snapshots
updated)

glitch with X-12
by Summers, Peter
Folks,
I just did some seasonal adjustment with the latest Windows snapshot (build date 10/8). With one series I got a warning about at least one significant trading day effect. I had a look, closed the warning box & adjusted the rest of my data. Some subsequent data also generated a warning, but the warning box was shrunk - just the triangle-exclamation point sign and a "close" button.

Thanks. This should now be fixed in CVS and shapshots.

Confirmed. Hopefully this should be a fairly quick fix.
