Lifelines 0.4.2

0.4.2

• Massive speed improvements to CoxPHFitter.
• Additional prediction method: predict_percentile is available on CoxPHFitter and AalenAdditiveFitter. Given a percentile, p, this function returns the value t such that S(t | x) = p. It is a generalization of predict_median.
• Additional kwargs in k_fold_cross_validation that will accept different prediction methods (default is predict_median).
• Bug fix in CoxPHFitter predict_expectation function.
• Correct spelling mistake in newton-rhapson algorithm.
• datasets now contains functions for generating the respective datasets, ex: generate_waltons_dataset.
• Bumping up the number of samples in statistical tests to prevent them from failing so often (this a stop-gap)
• pep8 everything
