Gretlwiki announcement
by DeFeroci
Dear all,
I would like to announce that the gretl wiki is back up and running at:
https://gretlwiki.econ.univpm.it/index.php/Main_Page
For security reasons (and previous experience) only registered users can
modify the wiki and self-registration is no longer possible. So, if you
want to be added, please write to me privately or reply to this email.
Information on how to be registered and using the wiki can be found here:
https://gretlwiki.econ.univpm.it/index.php/Wiki
At the moment the wiki administrators are me and Cristián Arturo Ducoing
Ruiz.
If you have any suggestions or requests, you are welcome to contact us.
Happy holidays.

Grid search
by Olasehinde Timmy
Dear profs.,
Please, I would like to know how to perform a grid search in order to find
an optimal value for a threshold—for example, the threshold value to choose
for the inflation rate in an asymmetric model.
Thanks.

Stock-flow consistent models

Can one set up a stock-flow consistent model a la Godley and simulate it in Gretl ? And how ?Von meinem/meiner Galaxy gesendet

missing values in fixed effects model
by heidinka8＠gmail.com
Hi, I have panel data made of 99 cross-sectional units and 7 time series. When I do the fixed effects model in gretl, there are only 158 observations, 56 cross-sectional units and 4 time series. My model has one dependent variable and 5 independent variables. There are some values missing and I have told this shoudn't be a problem while doing the linear regression. But gretl removed all of the units where there is only one variable missing. Even when I have data for all other 5 variables, gretl removed it from model completely because on is missing. This reduced my dataset significantly. Could you please advise how to fix this?

Thank you frederico and especially Sven for the answers, i asked because it is relatively easy to do in Eviews ... it would be good i think if it were equally easy in Gretl. Thanks Von meinem/meiner Galaxy gesendet

On the gretl web page I'm only seeing various relatively outdated
version of the PWT (probably they should be updated...), apart from the
fact that they don't seem to be in a formal panel structure. So how did
you get or make your gretl datafile?
thanks

It's the double sub-sampling for the first plot (year >= 1960
--restrict and a short list of countries) that's throwing gretl's
calendar. The subsequent plots are not restricted by time, only by
country (since you use --restrict --replace with smpl). The first plot
works if you use the panel-specific means of sampling in the time
dimension:
instead of: smpl year >= 1960 --restrict
do: smpl 1960 2019 --time

Hi Peter,
try this please:
<hansl>
set verbose off
clear
nulldata 20
series y = normal()
setobs 10 1:1 --stacked-time-series
panplot y --overlay --output=display
# Set calendar data
setobs 4 2020:1 --panel-time # quarterly obs.
panplot y --overlay --output=display # shows proper date now
</hansl>
The crucial point is to define the frequency and initial date.
Best,
Artur

Peter, what is the time periodicity of your panel dataset, annual? Can
you perhaps tell us which of the shipped example files in gretl are
closest to your situation?

panplot question
by Summers, Peter
Hi folks,
I'm creating a couple graphs using panplot, and I'd like to have the x-axis labels be the date (year), rather than the time period number. Is there a way to do that? (I realize that may be a gnuplot question.) More generally, would it be possible to incorporate panplot functionality into the plot...end plot environment?
Thanks,
Peter
