Methods

B

  • Parameters

    Returns Real

M_T

  • Parameters

    Returns Real

a

  • Returns Real

alpha

  • Parameters

    Returns Real

apply1

apply2

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

    Parameters

    Returns Real

covariance

deepUpdate

  • deepUpdate(): void

diffusion1

diffusion2

drift1

drift2

evolve1

evolve2

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

    Parameters

    Returns Real

expectation1

expectation2

factors

  • returns the number of independent factors of the process

    Returns Size

fmpInit1

fmpInit2

getForwardMeasureTime

  • getForwardMeasureTime(): Time

init

initialValues

  • initialValues(): Real[]

setForwardMeasureTime

  • setForwardMeasureTime(t: Time): void

sigma

  • Returns Real

size

stdDeviation1

stdDeviation2

time

  • time(d: Date): Time
  • 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.

    Parameters

    • d: Date

    Returns Time

update

  • update(): void

variance
