class SwaptionPricingFunctionDetailed Description
Two-additive-factor gaussian model class.This class implements a two-additive-factor model defined by [ dr_t = nd $ y_t $ are defined by [ dx_t = -a x_t dt + igma dW^1_t, x_0 = 0 ] [ dy_t = -b y_t dt + igma dW^2_t, y_0 = 0 ] and $ dW^1_t dW^2_t = ho dt $.
Bug
- This class was not tested enough to guarantee its functionality.
