from_lifelines

survival.from_lifelines(fitted_model, *, label=None)

Build a SurvivalCurve from a fitted parametric survival model.

Reads the model’s own cumulative_hazard_at_times method, so the curve matches the fit exactly whatever family was chosen. Because the resulting cumulative hazard has no closed-form inverse in general, sampling from it falls back to heormodel.survival.curve.numeric_inverse_cumulative_hazard.

Parameters

Name	Type	Description	Default
fitted_model	FittedSurvivalModel	A fitted parametric survival model, for example the result of `lifelines.WeibullFitter().fit(durations, event_observed)`.	required
label	`str` \| None	Description of the curve for `repr`. Defaults to the fitted model’s class name.	`None`

Returns

Name	Type	Description
	SurvivalCurve	A `SurvivalCurve` at the model’s point estimate.

Example

from lifelines import WeibullFitter # doctest: +SKIP fit = WeibullFitter().fit(durations, event_observed) # doctest: +SKIP curve = from_lifelines(fit) # doctest: +SKIP

# from_lifelines { #heormodel.survival.from_lifelines }

```python

Build a `SurvivalCurve` from a fitted parametric survival model.

Reads the model's own `cumulative_hazard_at_times` method, so the curve
matches the fit exactly whatever family was chosen. Because the resulting
cumulative hazard has no closed-form inverse in general, sampling from it
falls back to `heormodel.survival.curve.numeric_inverse_cumulative_hazard`.
