Calculations

These methods must be implemented in derived classes to perform the actual calculations. When they are called, range check has already been performed; therefore, they must assume that extrapolation is required.

template<class Interpolator>
class QuantLib::InterpolatedAffineHazardRateCurve< Interpolator >

DefaultProbabilityTermStructure based on interpolation of a deterministic hazard rate component plus a stochastic one factor rate.

Member Function Documentation

◆ conditionalSurvivalProbabilityImpl()

Probability conditionalSurvivalProbabilityImpl ( Time  tFwd,
Time  tTarget,
Real  yVal 
) const
protectedvirtual

Probability of default conditional to the realization of a given value of the stochastic part of the hazard rate at a prior time (and thus to survival at that time). \( P_{surv}(\tau>tTarget|F_{tFwd}) \)

Reimplemented from OneFactorAffineSurvivalStructure.
