Detailed Description

Hybrid Heston Hull-White stochastic process.

This class implements a three factor Heston Hull-White model

Bug

This class was not tested enough to guarantee its functionality... work in progress

Member Function Documentation

void update () [virtual]

This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.

Reimplemented from StochasticProcess.
