The SVJJProcess command creates a new stochastic volatility process with jumps (SVJJ). This is a process governed by the stochastic differential equation (SDE)
r is the risk-neutral drift,
θ is the long-run mean of the variance process,
κ is the speed of mean reversion of the variance process,
σ is the volatility of the variance process,
δ is the volatility jump size,
W⁡t is the two-dimensional Wiener process with instantaneous correlation ρ,
N⁡t is a Poisson process, independent of W⁡t, with constant intensity λ,
J is a lognormal random variable with mean α and variance β2.
The parameters μ, α, and β are related by the following equation
This process was introduced by A. Matytsin. Special cases of this process include
Bates SVJ process
Heston SV process
First construct an SVJJ process with variable parameters. You will assign numeric values to these parameters later.
