Detailed Description

template<class Interpolator1D> class QuantLib::InterpolatedYoYOptionletVolatilityCurve< Interpolator1D >

Interpolated flat smile surface.

Interpolated in T direction and constant in K direction.

Constructor & Destructor Documentation

InterpolatedYoYOptionletVolatilityCurve (Natural settlementDays, const Calendar & cal, BusinessDayConvention bdc, const DayCounter & dc, const Period & lag, Frequency frequency, bool indexIsInterpolated, const std::vector< Date > & d, const std::vector< Volatility > & v, Rate minStrike, Rate maxStrike, const Interpolator1D & interpolator = Interpolator1D())

calculate the reference date based on the global evaluation date The dates are those of the volatility ... there is no lag on the dates but they are relative to a start date earlier than the reference date as always for inflation.

Member Function Documentation

Volatility volatilityImpl (Time length, Rate strike) const [protected, virtual]

implements the actual volatility calculation in derived classes For the curve strike is ignored because the smile is (can only be) flat.

Implements YoYOptionletVolatilitySurface.
