| Probability survivalProbabilityImpl | ( | Time | ) | const [protected, virtual] |
probability of survival between today (t = 0) and a given time
implemented in terms of the hazard rate 
as
![\[ S(t) = \exp\left( - \int_0^t h(\tau) d\tau \right). \]](form_369.png)
- Note:
- This implementation uses numerical integration. Derived classes should override it if a more efficient formula is available.
Reimplemented from HazardRateStructure.
