The fitted cumulative hazard at given times: lifelines' cumulative_hazard_at_times.

public double[] CumulativeHazard(ReadOnlySpan<double> times)

Parameters — times are the positive times to read at.

Returns — one cumulative hazard per time.

Example — for the Weibull, (t / λ)^ρ.

using Lodestar.Survival;

double[] months = [5, 8, 12, 3, 15, 9, 20, 6, 11, 14];
bool[] died = [true, true, false, true, true, true, false, true, true, false];

ParametricFit fit = ParametricSurvival.Fit(ParametricModel.Weibull, months, died);

double atTen = Math.Round(fit.CumulativeHazard([10.0])[0], 6);   // => 0.586406

Remarks — Survival is its exp(−H), so the two carry the same information; the hazard is the scale on which models are written, and on which CumulativeHazardBounds stays positive where the survival interval would not.

Applies to — net10.0, netstandard2.0.
