emacs mode for gretl
by ahmadou dicko
Hi everyone
This is my first post in this list, and i'm very grateful for those working
on this wonderful project so far, gretl is very great. I (already started)
would like to promote the use of this software in my school in Senegal.
But I'm also a R user and one thing Gretl lack is a complete emacs mode
like the ESS R-mode, with the gretlcli console as inferior-process, i'm
aware of the gretl-mode (which is great) but as far as I know it's not
interactive, for example you can't send line or block of code to an
inferior process...such mode can be great to learn hansl.
My elisp skill is not good enough to write a comint-mode, i started one
based on Octave-mode el file but it doesn't work.
I want to know if it's possible to create such mode using the gretcli or if
there are other possibilities ?
Any advice, hint, help or documentation on how to create such mode will be
greatly appreciated
I use ubuntu 11.10, gretl 1.96 and emacs 23.3
cheers

by Samantha buxton
Hi

would write a script for them.
I have attached a file as they do not want to copy over and it is very
diffucult to write them correctly in an e-mail
Thanks

Exact collinearity and modprint
by Giuseppe Vittucci
Dear all,
when in a regression one or more variables are omitted due to exact
collinearity, the command modprint leads to misleading results cause the
initial list of regressors does not match the vector of coefficients
returned by gretl.
Is there a way to retrieve the list of regressors dropped by gretl or
the list of regressors eventually used in the regression?
Thanks

GUI to quantreg
by Sergio Pastorello
Dear all,
it seems to me that the GUI to the quantreg command is broken in release
1.9.6. I tried to replicate the example on p. 252 of the User's Guide, but
I got an "Invalid quantile specification" error message. However, the
quantreg command still works perfectly when invoked from the console.
Also, the GUI works fine in release 1.9.5.
Is there a problem, or am I missing something?
Many thanks you for your help

Bug-hunting: Syntax highlighting
by Henrique Andrade
Dear Allin,
Please take a look into the pdf files attached. As one can see, there's
something wrong with the "colorido.pdf" file (lines between 73 and 197
weren't printed out in Windows Vista).
Best regards, Henrique

How to in Gretl
by Sam Buxton
Hi all,
I am having problems doing a number of things in gretl. I was just
wondering if anyone could help if they know how to produce the following
models in gretl
1) exponential smoothing
2) moving average
3) naive model
4) bass diffusion model.
Thanks a speedy response would be greatly apprecieated.
Sam

Sorry for the noise: (1) I forgot to send my previous message to the
users' list; (2) there was a small glitch in func2 (corrected below); (3)
I'd like to express my point more explicitly: IMO, base types such as
matrices should stay as unencumbered by extra info (or metadata, call it
what you want) in the interest of efficiency. If you really need to wrap
up a complex set of information into one entity, that's exactly what
bundles are for.
