Given that the library contains excellent VAR and DAR implementations, a Dynamic VAR class would be a great addition. The Statsmodels version hasn't been maintained for a long time (currently broken), so as far as I know there's no (working) open source Python implementation.
That would be nice. Unfortunately realistically I am not going to have time to build this, but if you are up for it then you can look at how the existing models are constructed and base it on that?
