Detailed Description

template<class Interpolator> class QuantLib::InterpolatedHazardRateCurve< Interpolator >

interpolated hazard-rate curve

Member Function Documentation

Probability survivalProbabilityImpl (Time) const [protected, virtual]

probability of survival between today (t = 0) and a given time

implemented in terms of the hazard rate $ h(t) $ as [ S(t) = \xp


:
This implementation uses numerical integration. Derived classes should override it if a more efficient formula is available.

Reimplemented from HazardRateStructure.
