Detailed Description

template<class Interpolator2D>
class QuantExt::StrippedCPIVolatilitySurface< Interpolator2D >

Stripped zero inflation volatility structure.

The surface provides implied CPI Black volatilities for the union of strikes that occur in the underlying cap and floor price surface.

The type argument determines which kind of price quotes are used with priority when there is an overlap, i.e. strikes for which we have both cap and floor quotes: If type is Cap: Use cap quotes where available, floor quotes otherwise If type is Floor: Use floor quotes where available, cap quotes otherwise If type is CapFloor: In case of overlap, use floor quotes up to the ATM strike, cap quotes for strikes beyond ATM
