Detailed Description

EQ Black Scholes parametrizations.

Base class for EQ Black Scholes parametrizations

Constructor & Destructor Documentation

EqBsParametrization	(	const Currency &	eqCcy,
		const std::string &	eqName,
		const Handle< Quote > &	equitySpotToday,
		const Handle< Quote > &	fxSpotToday,
		const Handle< YieldTermStructure > &	equityIrCurveToday,
		const Handle< YieldTermStructure > &	equityDivYieldCurveToday
	)

The currency refers to the equity currency, the equity and fx spots are as of today (i.e. the discounted spot)

virtual Real variance ( const Time t ) const

pure virtual

must satisfy variance(0) = 0.0, variance'(t) >= 0

Real sigma ( const Time t ) const

virtual

is supposed to be positive

Size numberOfParameters ( ) const

overridevirtual

the number of parameters in this parametrization

Reimplemented from Parametrization.
