> I am talking about the Lorenz attractor. You are correct that the system is considered deterministic. But this attractor behaves in different way based on the initial conditions. In my exapmle, the initial conditions are not deterministic and there is noise associated with the third state as well as to the output of the system. As such the system is modelled as uncertain.I am plotting the PDF for this system.Did you get my question??

  The Lorenz oscillator itself is deterministic, so all probabilistic questions of its behavior are dependent entirely on the statistics of initial condition variation and parameter variation, and you haven't given us any information about those.  Given that omission, how could you possibly expect a valid answer to your question?
