[Gretl-devel] Re: old and new ideas for the next 'extra' addon version

Hi,
here are some thoughts about a next round of updating 'extra'. Reminder:
"The extra package (a collection of various convenience functions for
hansl programming)". It comes as an add-on which means it is
automatically shipped with each gretl installation. All items including
their names and so on are open for discussion.
1) drawnormwis(): This function does a random draw from
Normal-inverse-Wishart distributions for Bayesian stuff and currently
exists hidden in the SVAR addon (see
https://sourceforge.net/p/gretl/git/ci/master/tree/addons/SVAR/SVAR_compa...)
It could go in "as is", unless somebody has suggestions or ideas.
Hi Sven,
just one suggestion. The function name may be modified to make more
clear what it's for. We already have the built-in function iwishart().
So why not name the proposed function drawnormiwishart()? Personally I
would even name it drawnormal_iwishart() for readability purposes.
2) multiplot(): I'm attaching an unfinished but working
prototype. Many
many things could be added here, this is a bit like Pandora's box (or
the work of Sisyphus?). But maybe having _something_ is better than
nothing? Feedback please!
I could have a look at it during the next 2 days.
3) fill() or fill3D() or whatever: Would be the inverse of drill(),
i.e.
“shoves” a 1-dim vector with N elements
into an N-element matrices array (in each i,j position), so in the hole
left by drill(), so to speak. Would be easy to arrange, but is there
really a need?
Nothing to say on this, sorry.
