v0.23.4

Bugfix for PyPI

v0.23.3

0.23.2

New features

• StatisticalResult.print_summary supports html output.

Bug fixes

• fix import in printer.py
• fix html printing with Univariate models.

v0.23.2

0.23.2

New features

• new lifelines.plotting.rmst_plot for pretty figures of survival curves and RMSTs.
• new variance calculations for lifelines.utils.resticted_mean_survival_time
• performance improvements on regression models' preprocessing. Should make datasets with
  high number of columns more performant.

Bug fixes

• fixed print_summary for AAF class.
• fixed repr for sklearn_adapter classes.
• fixed conditional_after in Cox model with strata was used.

v0.23.1

0.23.1

New features

• new print_summary option style to print HTML, LaTeX or ASCII output
• performance improvements for CoxPHFitter - up to 30% performance improvements for some datasets.

Bug fixes

• fixed bug where computed statistics were not being shown in print_summary for HTML output.
• fixed bug where "None" was displayed in models' __repr__
• fixed bug in StatisticalResult.print_summary
• fixed bug when using print_summary with left censored models.
• lots of minor bug fixes.

v0.23.0

0.23.0

New features

• new print_summary abstraction that allows HTML printing in Jupyter notebooks!
• silenced some warnings.

Bug fixes

• The "comparison" value of some parametric univariate models wasn't standard, so the null hypothesis p-value may have been wrong. This is now fixed.
• fixed a NaN error in confidence intervals for KaplanMeierFitter

API Changes

• To align values across models, the column names for the confidence intervals in parametric univariate models summary have changed.
• Fixed typo in ParametricUnivariateFitter name.
• median_ has been removed in favour of median_survival_time_.
• left_censorship in fit has been removed in favour of fit_left_censoring.

v0.22.10

0.22.10

The tests were re-factored to be shipped with the package. Let me know if this causes problems.

Bug fixes

• fixed error in plotting models with "lower" or "upper" was in the label name.
• fixed bug in plot_covariate_groups for AFT models when >1d arrays were used for values arg.

v0.22.9

0.22.9 - 2019-10-30

Bug fixes

• fixed predict_ methods in AFT models when timeline was not specified.
• fixed error in qq_plot
• fixed error when submitting a model in qth_survival_time
• CoxPHFitter now displays correct columns values when changing alpha param.

v0.22.8

0.22.8

New features

• Serializing lifelines is better supported. Packages like joblib and pickle are now supported. Thanks @AbdealiJK!
• conditional_after now available in CoxPHFitter.predict_median
• Suppressed some unimportant warnings.

Bug fixes

• fixed initial_point being ignored in AFT models.

v0.22.7

Changelog

0.22.7

New features

• new ApproximationWarning to tell you if the package is making an potentially bad approximation.

Bug fixes

• fixed a bug in parametric prediction for interval censored data.
• realigned values in print_summary.
• fixed bug in survival_difference_at_fixed_point_in_time_test

API Changes

• utils.qth_survival_time no longer takes a cdf argument - users should take the compliment (1-cdf).
• Some previous StatisticalWarnings have been replaced by ApproximationWarning

v0.22.6

0.22.6

New features

• conditional_after works for CoxPHFitter prediction models 😅

Bug fixes

API Changes

• CoxPHFitter.baseline_cumulative_hazard_'s column is renamed "baseline cumulative hazard" - previously it was "baseline hazard". (Only applies if the model has no strata.)
• utils.dataframe_interpolate_at_times renamed to utils.interpolate_at_times_and_return_pandas.
