I've written a method for getting the survival function until timestep $t$ where $0
Thanks for the great package! I was going over this tutorial https://dataorigami.net/2020/08/03/SaaS-churn-and-piecewise-regression-survival-models.html but I am facing issues with AttributeError: 'PiecewiseExponentialRegressionFitter' object has no attribute '_norm_mean' I checked the source code...
The `print_summary` method in the `lifelines.statistics.StatisticalResult` class was not correctly handling the `decimals` argument when no explicit `style` was provided. This led to the output table displaying the default precision...
Hi, Thank you for the excellent package! As I'm learning about the AFT model, I have some naive questions about your implementation of AFT, and hopefully you can help me...
Hi team, I found that when you fit a very imbalanced dataset, the CoxPHFitter models led to a singular error because the k_fold_cross_validation does not ensure the folds include both...
ONNX export (e.g. with https://onnx.ai/sklearn-onnx/ ) would be very beneficial for deploying trained models to any environment and programming language. Do you have such export options considering ONNX is the...

Hey! I would like the results of the add_at_risk_counts to be saved as an array or something instead of it just being part of my plot. Is there any way...
Currently, lifelines only supports pandas for its operations. It would be great if there was polars support. It might be interesting to look into [narwhals](https://github.com/narwhals-dev/narwhals) which allows projects to support...
**Title:** CoxTimeVaryingFitter should warn when subjects don't start at time 0 + unclear documentation **Issue Type:** Enhancement/Documentation **Description:** The `CoxTimeVaryingFitter` documentation is unclear about the expected format of start/stop times,...
