CamDavidsonPilon/lifelines: v0.22.1

0.22.1 New features New univariate model, GeneralizedGammaFitter. This model contains many sub-models, so it is a good model to check fits. added a warning when a time-varying dataset had instantaneous deaths. added a initial_point option in univariate parametric fitters. initial_point kwarg is present in parametric univariate fitters .fit event_table is now an attribute on all univariate fitters (if right censoring) improvements to lifelines.utils.gamma API changes In AFT models, the column names in confidence_intervals_ has changed to include the alpha value. In AFT models, some column names in .summary and .print_summary has changed to include the alpha value. In AFT models, some column names in .summary and .print_summary includes confidence intervals for the exponential of the value. Bug fixes when using censors_show in plotting functions, the censor ticks are now reactive to the estimate being shown. fixed an overflow bug in KaplanMeierFitter confidence intervals improvements in data validation for CoxTimeVaryingFitte
