Thanks for the report. That's now fixed in CVS. Just for the
record, that was a GUI-specific problem: the setobs command would
correctly adjust the n and T values for the panel in this case.

Thanks, I'll take a look at that tonight.

Can you give an example of how a non-Portuguese speaker can
recognize which Portuguese variant is being used? If I know how to
tell the difference I can try testing on OS X.

Problems with language preference
by Henrique Andrade
Dear Gretl Community,
I've installed the latest Gretl snapshot (Mac version) and
Gretl stopped to use Brazilian Portuguese. The interesting
fact is that I had made no changes in the Gretl preferences.
Now, even if I choose the option "Automatic" or "Portuguese
(Brazilian)" Gretl uses the Portuguese (from Portugal).
Is anyone experiencing this behavior?
Best,

You need to (a) fill in the holes in your data set, or (b) choose
a smaller sample that contains no missing values after defining
the lags.

panel plot

Dear Allin,
It seems like in the "panel plot" window, both options on boxplot do
produce the same graph.

re-organizing panel data
by artur bala
Dear Allin,
I have a 5 x 12 panel data that I processed, by mistake, as a 6 x 10 panel.
Well, I tried to re-organize the panel structure but if I go through the
"stacked time series" option no change takes place. Instead, if I select
the "stacked cross section" everything works fine.
regards,
artur

Testing for autocorrelation doesn't tell you anything about
simultaneous equations bias.
But if the DW test is not reported that suggests that either the
time-series length is too short or there are missing values within
the sample. If the problem is missing values and you're willing to
ignore that issue, you could save the residuals (they're available
as $uhat) and construct a test (Durbin-Watson or otherwise)
manually -- e.g. by setting the missing residuals to zero.

GMM Instruments Lagged Independent Variables
by Dempsey, Keely
Hello,
I am trying to estimate GMM using lagged (-1) values of the two independent variables in my equation as instruments. When I try to estimate an error message saying "missing values" appears. Does anyone know how to correct this?
Thank you
