Creating autoMMM library based on your code. about mmm_stan HOT 2 CLOSED

Hi Nick,

I'm thrilled to know you're creating a library based on this!

I'm not sure about the generability of my code. It was created for this dataset, and will yield only a baseline model. In practice, MMM is very versatile, a couple of things need to be customized and tuned to fit a specific case.

1. Variables. This model: sales ~ impressions, while someone prefers sales ~ spend (combine model2 and model3), someone has monthly data, etc.
2. Priors. I used relatively strong priors for coefficients because I normalized the variables. If a user chooses not to normalize the variables, he may need to switch to weaker priors.
3. Additive or multiplicative model structure.
4. Adstock parameters need tuning. See #15 for details.

How far do you want to go, what's your plan? And let me know how I can help. I could work on it on weekends and in free time.
