Lifelines Versions Save

0.28.0 - 2023-01-03

• Fixes bins that are far into the future with using survival_table_from_events, see #1587
• Removed sklean_adaptor. It was a terrible hack, and causing more confusion and support debt than I want. This cleans up our API and simplifies the library. ✨ There's no replacement, and I doubt I'll introduce one ✨
• Fix pandas>=2.0 compatibility.
• Fix overflow issue in NelsonAalenfitter, #1585
• officially drop support for < py3.9
• update some dependencies (pandas >= 1.2)

• Fixed some deprecation warnings
• Pinned to numpy < 2.0

0.27.7 - 2023-05-01

• check_assumptions(show_plots=True) will always show plots, regardless of test outcome. Thanks @nomennominatur!
• lifelines.datasets is now importable.

• Support pandas 2.0+

0.27.4 - 2022-11-16

0.27.3

New features

• Fixed and silenced a lot of warnings

Bug fixes

API Changes

0.27.2 - 2022-09-07

Bug fixes

• Fixed issue in add_at_risk_table when there were very late entries.

0.27.1 - 2022-03-15

New features

• all fit_ methods now accept a fit_options dict that allows one to pass kwargs to the underlying fitting algorithm.

API Changes

• step_size is removed from Cox models fit. See fit_options above.

Bug fixes

• fixed Cox models when "trival" matrix was passed in (one with no covariates)

0.27.0 - 2022-03-15

Dropping Python3.6 support.

Bug fixes

• Fix late entry in add_at_risk_counts.

New features

• add_at_risk_counts has a new flag to determine to use start or end-of-period at risk counts.
• new column in fitter's summary that display the number the parameter is being compared against.

API Changes

• plot_lifetimes's duration arg has the interpretation of "relative time the subject died (since birth)", instead of the old "time observed for". These interpretations are different when there is late entry.

New features
