Looking for modeling renewal process with lifelines

[Himscipy]

Hi @CamDavidsonPilon,

Thanks for the wonderful package. I wanted to understand if the package provide any provision to model renewal processes. The one described in this paper "https://arxiv.org/pdf/0708.0362.pdf". It will be helpful if you could direct me to the development options if available in the package to develop the idea described in the paper for repairable systems.

Thank you for your time and consideration.

Hi @Himscipy - this seems like a great introduction to the subject of renewal processes! There's not support in lifelines yet, but it's been on my "wouldn't it be great if lifelines could..." list.

I don't know a good entry point for these models in lifelines. However, I would suggest building-up a few simple models by modelling their likelihood, and using autograd + scipy to "solve" them. I go through an example of this for survival models here: https://github.com/CamDavidsonPilon/PyDataNY_2019_tutorial

With that, it will be easier to wrap classes / lifelines pieces around that logic to later incorporate into lifelines (or make your own package with it!)
