Detailed Description

Square-root stochastic-volatility Bates process.

This class describes the square root stochastic volatility process incl jumps governed by ht \nd{array} ]

Member Function Documentation

Disposable<Array> evolve (Time t0, const Array & x0, Time dt, const Array & dw) const [virtual]

returns the asset value after a time interval $ Delta t $ according to the given discretization. By default, it returns \ where $ E $ is the expectation and $ S $ the standard deviation.

Reimplemented from HestonProcess.
