Can lifelines call a frailty model?

Can lifelines call the frailty model? If so, I would appreciate any help with the exact method or code. If not, is there an alternative method.

The Cox frailty model? No, it's not implemented. It's a lot of work to implement, and I've just not had time to do so.

Thank you for your answer. Then is there a similar model in the library that can take into account heterogeneity?

Hi, I have seen recently someone using the cluster argument to pass the subject_id as a way to introduce the frailty concept (https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/1970/1550). Is this working according to you? If so, can we pass more than one clustering levels? Thanks!
