RestrictedMeanResult

The restricted mean survival time of a curve, with its variance: what KaplanMeier.RestrictedMean returns.

public sealed record RestrictedMeanResult(double Mean, double Variance)

Properties — Mean is the area under the survival curve up to the horizon, lifelines' RMST. Variance is the restricted second moment less the squared mean, as lifelines defines it.

Example — one subject, dead at time two: two time units of survival, all of them certain.

using Lodestar.Survival;

RestrictedMeanResult result = KaplanMeier.RestrictedMean(KaplanMeier.Estimate([2], [true]));

double mean = result.Mean;          // => 2
double variance = result.Variance;  // => 0

Remarks — the variance is that of the survival time restricted to the horizon under the fitted curve, not the sampling variance of the mean; lifelines names it the same way.

Applies to — net10.0, netstandard2.0.
