This was the task given during learning pseudocode basics. I'd like to estimate the predictability of a time series that is possibly chaotic. For this reason, I thought that the Lyapunov exponents would be a good candidate. I've done some research on the Internet but the explanations that I've found are not enough (at least to me) to implement it in Java.

Do you know where I could get a detailed algorithm/pseudocode for the Lyapunov exponent's estimation for time series? Alternatively, other measurements of time series predictability are welcome.
