Time-variant covariates

[lixgl]

Hey team,

Was wondering if we can add time-varied covariates for CLV Pareto/NBD model as noted by recent research here?

Hey @lixgl,

This model was mentioned in another discussion, with a link to the full research paper containing the appendix. We decided against adding this particular model because the researchers acknowledged its high complexity and extraordinarily slow fit times, but there are alternatives.

I'm planning to start work on adding time-varying covariates to the BG/NBD model later this year, and that same research note also contains a section on how the seasonality can be added to the current CLV models.
