Hey There! Thanks for your reply
I have not considered at this time to re-write as a state space, that’s an excellent point! My model is a dirichlet varmax technically, so its worth a shot just starting from the ground up and going from there! My main goal yesterday was to work on functions to help me model the additive log transform of the data + extract predictions
i’lll make an attempt today and edit this post if I make progress! thank you so much for your rec!
