Expand description
Kaplan–Meier survival curve (ISL ch 11.3) — the nonparametric estimate of the
survival function S(t) from right-censored event times.
At each distinct event time tᵢ, S drops by the factor (1 − dᵢ/nᵢ), where
dᵢ is the number of events at tᵢ and nᵢ the number still at risk
(time ≥ tᵢ). Censored observations leave the risk set without an event.
