[Gretl-users] Variable name and future requests
Thank you very much for your answer.
I will be very greatefull if you expand variable name box.
I'm using Gretl from Wake Forrest University and I must say that plenty of
things are made in last years. Good work guys.
But I also have some new suggestions for you...new features requests:
1. Data interpolation but from lower to high frequency data. Example from
quarterlly to monthly.
2. The possibility to include exogenous variables in VAR/VECM.
3.Var inverse roots graph but followed with textual pop-up menu. It's
difficult to see if some value is on or out the unit circle if it is close
to the line.
4.FEVD followed by graph.
5. More stability tests for VAR/VECM (Cusum, breakpoint, 1-step Chow test,
etc.)
6. F-tests of zero restrictions (Wald type Granger causality) for VECM.
This are only the suggestions. I know that you have plenty of work and
unfortunatelly I'm not a programer so I can't help you.
Your comments are welcome!

I agree. In fact, I'd make it 32 characters. I can't see any technical
impediment, except going through the code to double-check everything will
be tedious and error-prone.
Allin, your opinion? If you agree, I can start working on this in the next
days.
I think this is basically a good idea (though I'd tend to go for 16
characters, not 32, for regular variable names). The main problem
is with the various output-printing functions. For both console
output and the output that goes to gui windows, everything is in a
fixed format. Many of the output functions would have to be
redesigned to avoid stuff breaking over lines given a wider variable
name field.
One possible redesign that would save width on numeric output fields
would be to print all numbers such as coefficients and standard
errors in a fixed width, as opposed to gretl's current practice of
using decimal-aligned numbers printed to a given number of
significant figures, using scientific notation only when absolutely
needed. But I think gretl's current numeric output is nice and easy
to read -- you can see the relative magnitude of coefficients at a
glance.
That said, I don't claim that gretl's current regression output is
perfect and I'm certainly willing to consider proposals for
redesign, within an 80-column format.
