I am not quite familiar with Mathematica. I am attempting to use below codes to simulate a Jump Diffusion process where the deterministic component is: miu-[Lambda]*k. For some reason I am getting several errors listed below.

Besides this, I would like to change the Jump Diffusion to be evaluated given a Binomial Distribution and jump size of -0.3, constant volatility of the jump.

The whole problem can be defined as:

dSt = (\[Micro] - \[Lambda]k) Stdt + \[Sigma]StdZt + Stdqt,  where dq is jump following binomial distribution and jump size is -0.3 

I am including the codes and errors hereby:

JumpD = TransformedProcess[(miu - \[Lambda]*k) t + \[Sigma] w[t] -      j[t], {w \[Distributed] WienerProcess[r, \[Sigma]],      j \[Distributed]       CompoundPoissonProcess[\[Lambda],        NormalDistribution[k, \[Delta]]]}, t];   data = RandomFunction[   JumpD /. {\[Sigma] -> 0.2, \[Lambda] -> 0.5, \[Delta] -> 0, r -> 0,      k -> 0.3, miu -> 0.3}, {0, 1, 0.003}, 20]  ListLinePlot[data]
