摘要

One frustration of data scientists and statisticians is moving between programming languages to complete projects. The most common two are R and Python. For example, a survival analysis model may be fit using R's survival-package Previously, this may have meant using Python libraries to call out to R (still shuffling between two languages, but now abstracted), or translating the fitted model to Python (likely to introduce bugs). Libraries like Patsy (Nathaniel J. lifelines extends the toolbox of data scientists so they can perform common survival analysis tasks in Python. Its value comes from its intuitive and well documented API, its flexibility in modeling novel hazard functions, and its easy deployment in production systems & research stations along side other Python libraries. The internals of lifelines uses some novel approaches to survival analysis algorithms like automatic differentiation and meta-algorithms. We present high-level descriptions of these novel approaches next.
