Constructor Detail

VarianceGammaModelDescriptor

public VarianceGammaModelDescriptor(LocalDate referenceDate,
                                    Double initialValue,
                                    DiscountCurve discountCurveForForwardRate,
                                    DiscountCurve discountCurveForDiscountRate,
                                    double sigma,
                                    double theta,
                                    double nu)

Parameters:

referenceDate - The date corresponding to the floating point date t=0.

initialValue - \( S_{0} \) - spot - initial value of S

discountCurveForForwardRate - The curve specifying \( t \mapsto exp(- r^{\text{c}}(t) \cdot t) \) - with \( r^{\text{c}}(t) \) the risk free rate

discountCurveForDiscountRate - The curve specifying \( t \mapsto exp(- r^{\text{d}}(t) \cdot t) \) - with \( r^{\text{d}}(t) \) the discount rate

sigma - The parameter \( \sigma \).

theta - The parameter \( \theta \).

nu - The parameter \( \nu \).
