◆ survivalProbabilityImpl()

Probability survivalProbabilityImpl ( Time t ) const

survival probability calculation implemented in terms of the hazard rate \( h(t) \) as

\[ S(t) = \exp\left( - \int_0^t h(\tau) d\tau \right). \]

Warning:: This default implementation uses numerical integration, which might be inefficient and inaccurate. Derived classes should override it if a more efficient implementation is available.
