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 am sure Allin and Jack will have your suggestions into account.
This message is to highlight that non programers (as myself) may
also help with a free software project as gretl:
1- Reporting bugs (probably the most important work)
2- Offering suggestions for ways to improve gretl.
3- Writing new documentation: tutorials, guides, etc.
4- Reporting about their way to use gretl (cases of study).
5- Translating to new languages or collaborating with the existent
translations.
