Detailed Description

experimental Black-Scholes-Merton stochastic process

This class allows to choose a built-in discretization scheme

Member Function Documentation

Real drift (Time t, Real x) const [virtual]

Possible enhancements

revise extrapolation

Reimplemented from GeneralizedBlackScholesProcess.

Real diffusion (Time t, Real x) const [virtual]

Possible enhancements

revise extrapolation

Reimplemented from GeneralizedBlackScholesProcess.

Real evolve (Time t0, Real x0, Time dt, Real dw) const [virtual]

returns the asset value after a time interval $ Delta t $ according to the given discretization. By default, it returns [ E(x_0,t_0,Delta t) + S(x_0,t_0,Delta t) dot Delta w ] where $ E $ is the expectation and $ S $ the standard deviation.

Reimplemented from StochasticProcess1D.
