I have no grasp on C programming but I used to program in Visual Basic a (rudimenatry) econometric software that I went proud of. I gave up when I knew about Gretl! Anyway, could you or anyone else recommand me any good book on C/C++ programming (in english, french or italian) or any other web resources, it should be a pleasure to invest my spare time (and much more than that) to be of any help in contributing to Gretl! It really deserves it!
Thanks once again, for having offered us a useful and great softawre!

Is it possible to get a windows recompile?
by Chris
The windows cvs compile has some arch forecast fixes i need to use, but is
also really crash prone. Would it be possible to get a recompile? maybe
current cvs is better.
Thanks,

arima forecasting
by walgula＠wp.pl
Hello, I'm trying to use an a raima model to forecasting.
How to write a script that forecasts forwards some variable?
I've dataset/file that includes "X" observations in time and i want to forecast this observation in time hour+1 or hour+2 forewards.
How to do it? I know that I should to use "fcast" or "fcasterr" functions, but i don't know how to get time parameters.
Please, help me.
Best regards, walgula

fcast arch bug?
by Chris
Hi,
When I try to use fcast after an arch command I get the error
? fcast fit2 --dynamic
Can't do this: no model has been estimated yet
but when I replace the "arch 24" with "ols" the fcast command works fine. Is
this a bug or am I missing something?
Thanks,
Chris

Re: GNU R with R2.5.0... a problem

This was due to a change in R 2.5.0: the "read.table" function has
been moved into the "utils" library. Gretl should now handle this
OK (in CVS and today's Windows snapshot). We check if the R
version is higher than 2.4.1, and if so we load the utils library
before calling read.table.

any work on allowing fcast to substitute different values?
by Chris
Hi,
I notice in the manual that there is no provision for fcast to substitute
different values for doing the forecast. Is anyone working on allowing this?
It would seem much neater to be able to specify the forecast X's seperately
rather than adding them to the end of the dataset and having to fiddle with
sample ranges.
Thanks,

Ang. [Gretl-users] t-distribution in p-value finder
by andreas.karlsson＠ltv.se
A noncentral t-distribution can have mean 3 and SD 4000, but not the usual
t-distribution.

t-distribution in p-value finder
by Sven Schreiber
Hi,
today I stumbled over the parameters for the t-distribution in the
p-value finder: Mean and SD apart from DoF. AFAIK there is no such thing
as a t distribution with, say, mean 3 and SD 4000. Or am I missing
something?
Thanks,

arima + arch ?
by Chris
is there any way to combine arima with arch? Is this a stupid question? When
I run the arima stuff I get a fantastic fit to the data, but when I run the
arch test it shows I definitely have an arch process.
Thanks,

multiple lines/curves in plots
by Talha Yalta
A quick suggestion:
- For the plots, would it be possible to have custom lines by entering
different values for the parameters? For example, in my plot, I have a
linear fitted line: y = a + b*x. It would be nice if I could enter 0.5
instead of "b" and compare the difference.
- Even better, would it also be possible to have multiple fitted (or
not) lines & curves in plots? I think upto 4 would be ideal but even 2
would be neat.
Cheers
Talha
PS: Of course, it is always quick to suggest a new feature as opposed
to actually implementing it but I think this might be a nice
improvement.
