Hi,
I wan�t to calculate the Lyapunov exponents of several time series (16 years
of weekly observations each with a strong seasonal component).
I�ve got a reference that compares three methods: Feedforward Neural
Networks, Thin-Plate Splines and Response Surface (Ellner & Turchin 1995,
American Naturalist 145(3),343-375).
How can I estimate Lyapunov exponents (global and local) in R by any or all
of this techniques?
Thanks for any advice,
Gregorio Fernandez
