Member Function Documentation

◆ x0()

Real x0 ( ) const

overridevirtual

returns the initial value of the state variable

Implements StochasticProcess1D.

Definition at line 45 of file merton76process.cpp.

◆ drift()

Real drift	(	Time	t,
		Real	x
	)		const

overridevirtual

returns the drift part of the equation, i.e. \( \mu(t, x_t) \)

Implements StochasticProcess1D.

Definition at line 50 of file merton76process.hpp.

◆ diffusion()

Real diffusion	(	Time	t,
		Real	x
	)		const

overridevirtual

returns the diffusion part of the equation, i.e. \( \sigma(t, x_t) \)

Implements StochasticProcess1D.

Definition at line 51 of file merton76process.hpp.

◆ apply()

Real apply	(	Real	x0,
		Real	dx
	)		const

overridevirtual

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

Reimplemented from StochasticProcess1D.

Definition at line 52 of file merton76process.hpp.

◆ time()

Time time ( const Date & ) const

overridevirtual

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

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

Reimplemented from StochasticProcess.

Definition at line 49 of file merton76process.cpp.

◆ stateVariable()

const Handle< Quote > & stateVariable ( ) const

Definition at line 53 of file merton76process.cpp.

◆ dividendYield()

Definition at line 57 of file merton76process.cpp.

◆ riskFreeRate()

const Handle< YieldTermStructure > & riskFreeRate ( ) const

Definition at line 61 of file merton76process.cpp.

◆ blackVolatility()

const Handle< BlackVolTermStructure > & blackVolatility ( ) const

Definition at line 66 of file merton76process.cpp.

◆ jumpIntensity()

const Handle< Quote > & jumpIntensity ( ) const

Definition at line 70 of file merton76process.cpp.
