1 | OUstepEuler(X_0, Dt, Mu, Th, Sig)
|
X_0 |
a matrix containing the starting value of each process |
Dt |
a numeric containing the timestep |
Mu |
a vector containing the unconditional expectation of the process |
Th |
a transition matrix, i.e., a fully generic square matrix that steers the deterministic portion of the evolution of the process |
Sig |
a square matrix that drives the dispersion of the process |
a list containing
X_t a vector containing the value of the process after the given timestep
Mu_t a vector containing the conditional expectation of the process
Sig_t a matrix containing the covariance after the time step
X_{t+ τ } = \big(I- e^{- θ τ } \big) μ + e^{- θ τ } X_{t} + ε _{t, τ }
