WebSep 6, 2004 · The hazard function h(t) is the conditional probability of dying at time t having survived to that time. The graph of S(t) against t is called the survival curve. The Kaplan–Meier method can be used to estimate this curve from the observed survival times without the assumption of an underlying probability distribution. The method is based on ... WebThe Weibull hazard function At its core, the Weibull distribution is defined by a simple hazard function. The hazard function, h(·), is the conditional density given that the event we are concerned about has not yet occurred.
