Is there any interest for supporting PMML (Predictive Modeling Markup Language) to allow models to be exported from gretl? Alternatively, importing data and variable information from PMML?
I'm tempted to close this and say: "It could always be implemented as a function package". But as this concerns data import and handling of saved models in the "model table" in gretl, I think there is a case that any changes would happen in core gretl.
That said, I have never heard about this PMML before. It would be good to hear from people who are actually using this, otherwise I may close this in the next round.
