Add Additional Expressions to sBG Model

I think adding `customer_lifetime_value` support for this model is a good idea, per https://github.com/pymc-labs/pymc-marketing/issues/527.

Add Codespaces config file?

@maresb I'm particularly interested to hear your thoughts.

Add Codespaces config file?

It can be used for both. A 2-core compute is fine for unit testing script changes, and is how I've kept my team's Python dev costs near zero for the...

Add Codespaces config file?

Thanks for responding @maresb! > Like does it even make sense to run jupyter/base-notebook here? Wouldn't it be more natural to use the VS Code Jupyter extension? We'd probably want...

Implement validation PPC plots for CLV models

I seem to have created a duplicate issue for this: https://github.com/pymc-labs/pymc-marketing/issues/326 This is highly relevant to the work I'm doing in https://github.com/pymc-labs/pymc-marketing/pull/327. The dev notebook in that branch even has...

Thanks @zwelitunyiswa!

List of Continuous, Non-Contractual `clv` Models to Consider Adding

Pinning this because it's a good list of models to add to the `clv` module and research reference. Also added a link to another paper comparing the Pareto/NBD, BetaGeo/NBD, PDO...
