skewness and kurtosis
by Annaert Jan
I know there are functions to compute the mean, median, minimum, maximum and standard deviation for a series. I also know that using the summary command, skewness and excess-kurtosis are also computed. Is there an easy way to capture these last two statistics (I need them for further processing)? Of course, I could write a short function to do this, but as they are already available in Gretl in the summary command…
Thanks,
Jan Annaert

Support to "xlsx" files
by Henrique Andrade
Dear Gretl developers,
I would like to make a simple suggestion that possibly requires a not so
easy/simple solution (in terms of coding effort): Add to Gretl support to
.xlsx files.
Best regards,
*Henrique Andrade*

Suitable use of libgretl?
by Matthew Wild
Hello gretl-users,
I'm looking to implement an application, and am wondering how best to
go about it. libgretl looks like it might be the answer, but I'm not a
statistics/machine-learning guy and would like a nudge in the right
direction.
I need to take multiple streams of data (integers) in real time for
which dependencies are not known beforehand. From the data streams I
need to infer dependencies and identify patterns, and mark data which
do not match the patterns with a high confidence.
As an example, stream A could be related to stream B by some function,
linear or otherwise. If B has a good history of increasing/decreasing
proportional to A, but then one day A decreases and B increases
(diverging from the established pattern), that data needs to be
marked.
I'm intrigued to know if gretl 1) does this out of the box (I suspect
I'd be too lucky) or 2) can help implement this thing, or 3) is
completely in the wrong domain for this kind of application.
Many thanks,
Matthew

Re: [Gretl-users] Causality, video

Dear Oliver
Yes, you can take the test of Granger, indirectly. I'm sending you a link video.
Congratulations to Allin and the list for all this tremendous work.

Best regards. César.

lists to plot
by artur bala
Hi all,
Is there a way to plot in the same graph pairwise series (xi, yi)?
I'm thinking to something like this:
list X = x1 x2
list Y = y1 y2
gnuplot Y X # plotting (x1,y1) and (x2,y2)
cheers,

on function arguments
by artur bala
Dear Allin,
Could it be possible for a function to pass a series as boolean? If the
series is provided it can act like a "- - by" flag.
Best,
