I'm looking for the equation that how the lifelines package calculates the log-likelihood of CoxPHFitter.

I read the lifelines documentation but cannot find where is it.

Any help would be appreciated!

Does this answer your question? How to compute partial log-likelihood function in Cox proportional hazards model? The linked question provides a formula. Anything very specific to a particular software package is off-topic on this site. If lifelines is open source, then the code is available for perusal. – EdM May 17 '22 at 11:35
@EdM Thanks for your help, I'm sorry about my off-topic question. I would take a perusal. Whatever, thanks! – Inundata May 17 '22 at 11:41
