Member Function Documentation

Real apply (Real x0, Real dx) const [virtual]

applies a change to the asset value. By default, it returns $ x + Delta x $.

Reimplemented from StochasticProcess1D.

Time time (const Date &) const [virtual]

returns the time value corresponding to the given date in the reference system of the stochastic process.


As a number of processes might not need this functionality, a default implementation is given which raises an exception.

Reimplemented from StochasticProcess.
